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?
I moved my Scale server into the next room, laundry room, just so it’s out of sight. Replacing reveryplay 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.

- 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.

- This has long been the interface bus used by most home users to connect their hard drives, and is supported by nearly every motherboard.
- Advanced power management levels80h and higher do not permit the device to spin down to save power.
- It’s self-hosted and self-managed, so data remains within your company network.Bank-Level EncryptionBanking-standard TLS 1.2 technology protects your computer from unauthorized access.
- 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.
At somewhat larger scales, a number of drives can be connected directly to a SAS (or SATA) controller PCIe card. But, if the number of ports on the motherboard is sufficient to your needs, this is the easiest way to connect the drives to the system. We are going to focus on some of the most popular for SATA and SAS drives.

Unfortunately, APM settings don’t persist between power cycles so if we wanted to change disk settings with APM they would need to be reapplied on every boot. Advanced power management levels80h and higher do not permit the device to spin down to save power. For example, a device may implement one power management method from 80h to A0h and a higherperformance, higher power consumption method from level A1h to FEh. To prevent parking more often that is useful (for a server, usually that choice would be “very rarely”), there are a couple ways to do it and which apply will depend on what the hard drive vendor’s firmware supports. With the SMART metrics captured by Prometheus, it’s fairly easy to write a query that will show how often a given disk is parking its heads. Since I use Prometheus to capture information on the server’s operation however, I can use that to monitor that my hard drives are doing well.
- 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.

- Secondly what are your disk monitoring refresh intervals and what do you use on your system to monitor SMART disk health?
- Hello,Like many users of Seagate Exos drives, I have found that they park their heads very aggressively, approximately every 2 minutes.

Direct Attached deployments require a bit more hardware and cabling. The NVMe interface is also extensible to allow operating over the network (where it is known as NVMe Over Fabric or NVMe-oF). NVMe on the other hand, supports multiple queues (often 64 queues, but the official specification allows for up to 65,536 queues) allowing for many commands to be run concurrently. 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.
However, I noticed that my HDD’s heads park (particulary Seagate Exos) every 3 minutes. ZFS is widely trusted for large-scale storage, but production environments expose design mistakes,… When dealing with critical data, you only get one chance to do it right. The status field is a bitmask supporting a number of different options, but the main ones we care about are 1 (OK), and 2 (FAULTED). When combined with a JSON parser like jq, this can be used to automate tasks for each disk.
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.
SAS disk reservations provide the ability to connect to the disk redundantly—or even across multiple machines—while ensuring it is only used by one of them at a time. SAS provides many more features than SATA does—including full duplex operations, advanced error recovery, multipath, and disk reservations. It too was an extension on an existing interface bus which offered greatly improved performance. SATA+AHCI improved data transfer speeds, simplicity of communication, and included abilities that we today take for granted, such as “hot swap” and command queueing. These concepts also apply to other operating systems, but the tools might differ slightly.
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.
The APM specification dating from 1992 includes some controls for hard drives, allowing a host system to specify the desired performance level of a disk and whether standby is permitted by sending commands to a disk. In addition to the above query types, SES also supports a number of commands, including activating the “locate” and “fault” LEDs if present, and the ability to individually power off drives. The first step is to map out the relationship between the physical chassis where the disks reside, and the logical devices enumerated by the operating system.
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.

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?

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.
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.
FreeBSD’s sesutil is a tool to interface with the SES devices on your system. You should also configure smartd to monitor your disks and send you alerts, which may give you advanced notice when a drive is starting to fail. These special boards, called SAS Expanders, reduce the total cabling required to provide power and signal pathways to all connected disks.

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.
