Hi

 

New around here, but hoping to get some help with another unusual issue with unraid in 6.8.3 and seagate SMR hard drives ST8000AS0002 (/dev/sdg and /dev/sdh), and unraid's disk settings. 

 

What's currently happening is in dmesg/ syslog, I find the below error messages by:

1. allowing things to idle on unraid, and either logging in to, or refreshing the webUI and experiencing long hangs populating "Unassigned Devices" - where these two SMR hdd's are currently mounted. 

 

2. by running  

/usr/bin/dd bs=1 count=48 skip=462 if=/dev/sdh 2>/dev/null | /bin/sum | /
bin/awk '{print }'

... on a terminal when those disks have been inactive for some time.

I do have unraid "Default spin down delay: to never", and I don't have anything setup per disk to spin down either.

 

I have managed to repeat it somewhat using hdparm -Y /dev/sdh or /dev/sdg, followed by -C to check the state. When the reported state comes back as "standby" and I make an attempt to read the hard drive (eg use the DD command above, or anything else, such as a ls, it hangs for ~10 seconds before it responds, followed by those messages in the syslog/dmesg.

  

root@Tower:~# hdparm -Y /dev/sdh

/dev/sdh:
 issuing sleep command
root@Tower:~# hdparm -C /dev/sdh

/dev/sdh:
 drive state is:  standby
root@Tower:~# hdparm -C /dev/sdh

/dev/sdh:
 drive state is:  active/idle
root@Tower:~# hdparm -Y /dev/sdh

/dev/sdh:
 issuing sleep command

Both of these hard drives pass smart tests and diags, and didn't have issues when coping the data off them to the array, nor in the previous enclosure - this has just started appearing after they've been 'idle'.

 

Unable to disable any "seagate" related power down stuff:

  

root@Tower:~# hdparm -Z /dev/sdg

/dev/sdg:
 disabling Seagate auto powersaving mode
 HDIO_DRIVE_CMD(seagatepwrsave) failed: Input/output error
root@Tower:~# hdparm -Z /dev/sdh

 

A friend has suggested to try them on an onboard controller, as mine is a LSI SAS2308 PCI-Express Fusion-MPT SAS-2 with already the latest firmware.

 

Any other ideas?

 

thanks,

Jonathan
