Hello everyone.

I have a home proxmox setup on an oldish Super Micro Opteron server.

Supermicro SC846 24 Bay
2 AMD Opteron Hex Core 2431 @ 2.4Ghz for total of 12 cores
49GB RAM
3 x Supermicro's SAT2-MV8 SATA controller (based on the Marvell Hercules-2 Rev. C0 SATA host controller)

I am running on latest VE 5.2-1 setup. the whole server seams to be OK over all
it is up and running well. I use ZFS mirror pools for everything,

boot volume(rpool) is 2x120Gb mirror.
Code: 
NAME                           USED  AVAIL  REFER  MOUNTPOINT
rpool                         57.9G  49.6G   104K  /rpool
rpool/ROOT                    46.1G  49.6G    96K  /rpool/ROOT
rpool/ROOT/pve-1              46.1G  49.6G  46.1G  /
rpool/data                    3.32G  49.6G   128K  /rpool/data
rpool/data/subvol-101-disk-2  3.32G  46.7G  3.32G  /rpool/data/subvol-101-disk-2
rpool/swap                    8.50G  57.9G   196M  -

additional local storage(pvstore) is 2x1TB HDD mirror
Code: 
NAME                           USED  AVAIL  REFER  MOUNTPOINT
pvstore                       19.6G   879G  13.1G  /pvstore
pvstore/iso                    104K   879G   104K  /pvstore/iso
pvstore/subvol-103-disk-1     3.32G  6.68G  3.32G  /pvstore/subvol-103-disk-1
pvstore/subvol-104-disk-1     1.75G  8.25G  1.75G  /pvstore/subvol-104-disk-1
pvstore/template              1.37G   879G  1.37G  /pvstore/template

and 2 ZFS volumes tank0 and tank1 for main shared storage use. this are bind-mounted into LXC container and shared from there for all users as NAS.

6x2TB HDD
Code: 
NAME                           USED  AVAIL  REFER  MOUNTPOINT
tank0                         1.02T  4.24T   977G  /tank0
tank0/share0                  71.4G  4.24T  71.4G  /tank0/share0

and 2x3TB HDD
Code: 
NAME                           USED  AVAIL  REFER  MOUNTPOINT
tank1                         1.56T  1.07T   728G  /tank1
tank1/share1                   871G  1.07T   871G  /tank1/share1


I had several 2TB disk at home and I also bought 4 drives at my office.
the 4 drives are DELL(Seagate) ata-ST2000NM0055-1V4104 models.
they all connected to the same controller card.
in the last 2 weeks I lost 2 of them one after the other.
when I do zpool status I get tank0 is degraded, drive ATAXXXXXXXXXXX not available.
since I run 3 vdevs 2 disks in mirror mode no data loos happens. and as I do have several 2TB spares I just replace the disks and resolver. but the disks are online and do not show any issues.
I can redo the partition table and they are working.

how can I trace the issue?
what is the best way to Burn-in test the disks before use ?


thanks....

here is the smart report from the last failed disk

You should run a smart test (full), to see if it will show something. And for ZFS, it will mark pools degraded when it even just might be timing issues. To find out you need to check the log files and the zfs events.
 
Hi,

As I see in your smartd values, you may have a problem:

191 G-Sense_Error_Rate 0x0032 097 097 000 Old_age Always - 6781

This could indicate some HDD mechanical problem, or maybe your server generate a lot of mechanical vibrations(case?). So watch this value and see if it will increase in time.
 
... and for burn test, I use this cookbook, using a desktop for at least 3x 24 hours :

- run smartctl -t -long /dev/sdx
- run badblocks -wsv /dev/sdx

Note: the badblocks it will be destroy any data, so be aware!

thank you guletz.

I have checked All of mine drives item 191.

ALL of the DELL drives show counts over 2000 so I suspect they all going bad.
I have no vibrations in the chassis as far as I can tell. all fans are medium speed low noise and PSU is ATX 760W low noise low vibration PSU.
out of 13 HDDs , not counting 2 System SSDs all other disks either show 0 count for param 191 or have no such param at all. I guess DELL drives are simply bad. have been laying around for few months at work. I bought them when I left for cheap.
no biggie. will just go to Micro-Center and get couple of 3TB instead and build a new pool.

thanks
