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. These communities are filled with knowledgeable individuals who can offer more personalized advice and help you navigate the complexities of long-term data storage.

• For drives made by Western Digital, the inactivity timer for parking the heads is called the idle3 timer.
• Experienced enterprise storage managers also keep extensive notes including the model number, SKU and/or URL for reordering, purchase order information, warranty end date, warranty URL, and any other useful information about each drive.
• Typical SAS connectors support up to 4 drives per “lane”, but with an expander up to 255 devices are possible.
• To do this, both devices must have the program installed and must allow access through the use of security keys.
• After you apply these settings the logs will be written to your SSD instead of being flushed to the disc array.

Unnamed devices can be specified by their specific SES device and element number. This greatly reduces the chance of getting it wrong when you (or the datacenter technician) physically pulls the disk. You can also reboot, and GEOM will pick up the multipath when it first tastes the disks during boot.

Other interfaces for remote storage include iSCSI, Fiber-Channel, Infiniband, RoCE, and others, but those specialized solutions are beyond the scope of this article. Serial Attached SCSI (SAS) is the most common interface for enterprise storage, first appearing in 2004. Serial ATA (SATA) is the familiar interface used for non-enterprise storage, and is an extension of the original ATA interface dating from the 1980s. In this article we will discuss some strategies and tools to make managing disk arrays on FreeBSD (and related platforms like TrueNAS Core) much reveryplay easier. It may be what you want is to enable HDD standby, which will “spin down” the drives when not in use
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.
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.
For ZFS users, automating fault responses with tools like ZED (ZFS Event Daemon) can simplify disk replacement and minimize downtime. Configuring your system to notify you when a disk has errors, or when the filesystem reports a degraded device, will ensure your system gets prompt attention when something goes wrong. Experienced enterprise storage managers also keep extensive notes including the model number, SKU and/or URL for reordering, purchase order information, warranty end date, warranty URL, and any other useful information about each drive. While the operating system typically provides device aliases based on the disk’s serial number, WWN, or some other static identifier, this does not provide all of the information you might want.
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.
The parking rate basically drops to zero at the time I updated the settings for the Seagate drives, and the Western Digital one hasn’t changed because it needs to be powered off to change that setting and I haven’t done so yet. The other slight annoyance when setting the idle3 timer on WD drives is that changes only take effect when the drive is powered on, usually meaning the host computer must be fully shut down and started back up for any changes to be seen- this makes experimentation to determine how raw timer values are interpreted a slower and more tedious process. Of particular note, WD Green drives ship configured to park the heads after only 8 seconds of inactivity which could notionally wear out the disk in a matter of months if the heads are cycling more-or-less continuously! For drives made by Western Digital, the inactivity timer for parking the heads is called the idle3 timer.
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.

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.
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.

Understanding Storage Protocols

• Obligatory word of warning – mucking with low-level drive settings like this can cause issues.
• While both SATA and SAS allow multiple commands to be issued at once to the device, these commands cannot actually be executed concurrently—instead, they are queued for sequential operation.
• Of the three disks that I decided need some attention, I have one Western Digital disk and two Seagate ones.
• It too was an extension on an existing interface bus which offered greatly improved performance.
• Non-Volatile Memory Express (NVMe) is a newer storage interface that is becoming very popular for flash storage devices.
• I noticed that even when doing nothing, I hear the sound of drives working every few seconds.

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).
