I moved my Scale server into the next room, laundry room, just so it’s out of sight. Replacing the drive is financially out of the question. I’m looking for a software solution, if possible, to make the HDD idling for most of the time when there is no load. Yeah, it’s not helping, thanks. Although it’s empty, so this is probably not the source of the constant HDD noise.
While I have been aware of this in my home server as well, it is easy to forget to ensure that disks are not silently killing themselves by cycling the heads. With modern, especially Enterprise grade hard drives being able to have hundreds of thousands of head park operations in their service life, is this really an isssue? With the tools presented here, the reader is well armed to react to failed disks and ensure that the wrong disk isn’t accidentally pulled. However, if a disk has died entirely, or a slot is empty, it might not have a device name. Sesutil can also be used to locate the disk in the physical array.While the SES data tells us that there is an 8 TB disk in Slot 06, it does not tell us which slot in the chassis corresponds to 06. Looking at a few items from the output, we can see the device names (/dev/da0 and /dev/da7 respectively) of the disks in Slot00 and Slot07.
The timer values specified are in milliseconds, so this example will park the disk heads after 30 minutes of inactivity. If we wanted to allow the disk to still park its heads but at minimum frequency, setting the APM value to 7Fh (hdparm -B 127) seems to be the correct choice. Of the three disks that I decided need some attention, I have one Western Digital reveryplay disk and two Seagate ones.
I noticed that even when doing nothing, I hear the sound of drives working every few seconds. I gave up and just built a Windows Storage Space with tiering and the drives are now effectively silent. I guess it depends on the drives, but don’t think you’ll find any software solution. My Seagate Exos enterprise drives make almost 0 noise actually. The system is never idle really, it’s a server. What causes the constant load on the disk?
If you need more advanced functionality than mpsutil provides, LSI provides their native tools sas2ircu and sas3ircu for FreeBSD. On my system, this command produces a bright red LED lit for that slot, physically highlighting the correct drive to replace. So, to activate the LED for the first disk displayed above, we first need to determine the enclosure handle number (0001), and then the slot number of the disk (03). This partitions each disk and labels the ZFS partition with the enclosure, slot, and serial number of the corresponding disk. As with a number of tools in FreeBSD, sesutil supports outputting JSON via the libxo library.
- Keeping it spinning but not accessing data is safer.
- Sesutil can also be used to locate the disk in the physical array.While the SES data tells us that there is an 8 TB disk in Slot 06, it does not tell us which slot in the chassis corresponds to 06.
- If you’d feel safer with a team of experts monitoring your storage, consider a ZFS Support Subscription.
- SATA disks plugged directly into the motherboard use an interface called AHCI which does not provide much in the way of advanced management features.
- It is fairly well-known among techies that hard drives used in server-like workloads can suffer from poor configuration by default such that they frequently load and unload their heads, which can cause disks to fail much faster than they otherwise would.
Storage Media Options
My question is – is there a way to tell if a certain disk suffers from the issue prior to purchasing? For the system I’m monitoring here, the SSD that it boots from has a wearout indicator sitting on 95 of 100 (only 5% of the rated life consumed), visibly unchanged for a long time so it’s not very interesting as an example. (The properties like ID_SERIAL_SHORT can be queried on a running system using udevadm info, such as udevadm info /dev/sdd to get the properties of the disk currently assigned ID sdd.) Somewhat more useful for monitoring is the smartmon_load_cycle_count_raw_value, which provides the actual number of load cycles that have been done. Secondly what are your disk monitoring refresh intervals and what do you use on your system to monitor SMART disk health?
It is fairly well-known among techies that hard drives used in server-like workloads can suffer from poor configuration by default such that they frequently load and unload their heads, which can cause disks to fail much faster than they otherwise would. My Seagate Archive SMR disk (which began life as an external hard drive and was retired from that role when it became too small to hold as much as I wanted to back up to it) apparently doesn’t support reporting EPC settings (since asking for them says so), and initially didn’t accept new values for the idle timers either. The Prometheus Node Exporter is the canonical tool for capturing machine metrics like utilization and hardware information with Prometheus, but it alone does not support probing SMART data from storage drives. While SSDs don’t have any heads to park, most do report a media_wearout_indicator that represents the amount of data written to the device in relation to the amount that it’s specified to accept before the Flash storage medium wears out.
When it comes to long-term data storage, there are several strategies and media types that Redditors recommend. It refreshes the disks SMART information every 5 min. ZFS and Btrfs both aim to modernize storage by combining filesystems and volume management, but… Monitoring and maintaining your storage media is one of the most important parts of keeping your data safe.
- For smaller numbers of drives, and for most home systems, the most common way the disks are attached is to the SATA controllers built into the motherboard.
- I will optimize settings later for the security/quietness tradeoff however, I’m very pleased with it for now.
- When building a storage system, there are many different ways the disks might be connected to the system.

SATA disks plugged directly into the motherboard use an interface called AHCI which does not provide much in the way of advanced management features. For smaller numbers of drives, and for most home systems, the most common way the disks are attached is to the SATA controllers built into the motherboard. Non-Volatile Memory Express (NVMe) is a newer storage interface that is becoming very popular for flash storage devices. Just download the executable file on both devices and run it to open the tool. At a glance, changing idle3 and EPC settings seems to have done the job nicely; here is the same graph of head park rates per disk as before, but on a smaller timescale that makes individual head parks visible. Seagate provide a “Seachest” collection of tools for manipulating their drives, but rather more usefully to users of non-Windows operating systems like Linux they also offer an open-source openSeaChest.
It’s hard to imagine why your drives are that loud! It’s a datacenter drive, very loud, so it’s still audible. For quietness, a noise reducing case, move it somewhere else, quieter drives, maybe SSD instead of hard drives, etc.
We can also see that the disk in Slot07 was recently swapped, and that Slot08 does not contain a disk and its locate LED is activated. SES provides a mechanism to query information from the enclosure, including temperature, fan speed, and status of power supplies. Many backplanes include support for SCSI Enclosure Services (SES).
In this case, there are at least two disks that I probably need to configure, since /dev/sde seems to be parking as often as about every 4 minutes (0.004 Hz) and /dev/sdc is only parking slightly less often. The smartmon_load_cycle_count_value metric seems like it would be the right one to query, but that actually expresses a percentage value (0-100) representing how many load cycles remain in the specified lifetime- on reaching 0 the disk has done a very large number of load cycles. It does support reading arbitrary metrics from text files written by other programs with its textfile collector however, which is fairly easy to integrate with arbitrary other tools.

Once you’ve done so, you must test delivery to your “real” inbox—you don’t want to learn that delivery isn’t working after your storage has already become unavailable! If you’d feel safer with a team of experts monitoring your storage, consider a ZFS Support Subscription. If you rely on manually checking on your storage periodically, you will regret it. Another important aspect of managing your storage system is configuring notifications. Klara recommends embedding these details directly into the ZFS vdev properties of each disk—a feature Klara created, which will become generally available in the upcoming OpenZFS 2.2 release. In these configurations, your system may or may not support features like individual “locate” and “fault” LEDs.

If your system has multipath SAS, each disk will be present more than once, and you should use the gmultipathcommand to deduplicate your disks and for labeling as well. FreeBSD supports a number of different ways to label the disk, depending on your use case. The map command displays all of the SES devices and each element (this is the nomenclature in SES) connected to them. Of course, all of this chassis management technology isn’t very effective without tools to make it usable. It also provides information about each slot in the enclosure (even if empty), including a flag to indicate if the device has recently been swapped.

Then, click on “Connect” to access the other device. Send it to the other user who has the program and they will be able to access and control your device. It is very popular among professionals who provide technical support. Remember, the key is to act quickly and use the right tools for your specific situation. These practices and tools should give you a solid starting point for recovering your deleted files.
Below we will discuss exactly how to do this with FreeBSD’s sesutil or the management tools for your HBA. Though a truism, it bears emphasizing that with a little planning, management and maintenance of storage systems can be made easier and safer. The total throughput possible from the connected disks is still limited by the number of lanes available, but this is likely the best approach in systems with more than a dozen disks.
Most Seagate disks have configurable Extended Power Conditions (EPC) settings that include timers for how long the disk needs to stay idle before entering various low-power modes. Disk vendors typically provide their own vendor-specific ways to do persistent configuration of power management settings, so it’s worth trying to use those instead so the desired configuration doesn’t depend on the host system applying it, instead being configured in the drive (but in some cases it might be desirable to have the host configure that!). To prevent parking the heads at all a value greater than 128 may do the job (254 is a common choice, as the highest-power setting available), but it’s possible that some disks won’t behave this way because the ATA specification refers only to spinning down the disk and does not specify anything about parking heads. Typical SAS connectors support up to 4 drives per “lane”, but with an expander up to 255 devices are possible. An eight lane controller can only directly attach to 8 disks, requiring more controllers (consuming additional PCI-E slots) to connect more drives. This has long been the interface bus used by most home users to connect their hard drives, and is supported by nearly every motherboard.
Using the no-op true command on other paths to that disk, will cause GEOM to re-”taste” the disk and see the label and automatically add the additional paths to the existing multipath. This will write a GEOM Multipath label to the last sector of the disk. Each SAS Expander will present as a new /dev/ses# device, so your system may have more than one.
