(SOLVED) blk_update_request: I/O error - Can't read/write to multiple disks

[strifev1]

I have been using Unraid for a month or so. Just paid for Plus. 

Everything was going good with my previous config but I wanted to upgrade my CPUs. Ordered a used Supermicro X10-DRi and dual E5-2670 v3s and 32GBs RAM. 

I installed these into the new server it ran fine for about two hours, then my appdata folder share disappeared. I checked logs and there were disc errors. No docker app could read or write to these discs. It's like they just disappeared. 

 

Jun  8 13:08:51 Tower kernel: blk_update_request: I/O error, dev sdh, sector 15628052880 op 0x0:(READ) flags 0x80700 phys_seg 6 prio class 0

Error in start up. 

 

Did some digging and upgraded my BIOS to the most up to date version. I use a LSI 9211-8i for an HBA controller. It's in IT mode and on version 20 firmware. 

Performed a Memtest and it completed successfully twice. 

 

Any pointers you could give me would be appreciated. I haven't started singling out hardware like RAM or CPUs but that is my next step. 

 

It's the same 3 drives. Disk 2 4 and 5 all fail xfs_repair with read/write errors. I've moved these discs to other slots but get the same errors. The other discs run xfs_repair without issue.

xfs_repair: read failed: Input/output error
cannot read inode 375616, disk block 375616, cnt 32

 

Thanks.

There are read errors with multiple disks, first thing to do is to update the LSI firmware, all p20 releases except latest one (20.00.07.00) have known issues.

I tested CPUs and RAM last night and the issue happened regardless of singling out this hardware.

Upgraded the LSI firmware to 20.00.07.00 and finally the xfs_repair for these three disks stopped failing.

 

My array wouldn't start after this for some reason. It'd freeze when getting to the Starting Services ... part. Found that it was just the webgui going down. Opening a in-private browser and was able to get to the site again and the array had actually started without issue. 

 

Anyways, thank you for the help. I was being stubborn about the firmware version and thought "SURELY a .07 upgrade wouldn't be the fix". How naive I was way back then, yesterday. 🙃

Hey, I know this is a little old.  Was wondering what kind of drives you have in the mix.  Were they all SATA drives or did you have a mixture of SAS drives as well?  I'm experiencing the same I/I errors with LSI 9211-8e 20.00.07.00 in IT mode.  I have both SAS and SATA drives on the same backplane with a single expander (Supermicro BPN-SAS2-846el1.  I have read you shouldn't mix SAS and SATA drives on the same expander in the way array.  But I've also read others having success with this.  I am in process of separating them out to see if this will fix my issue.

Hey Tim,

I do have a mixture of sata and sas on a single backplane, fewer sas drives thab sata but I haven't had any drive errors like this since upgrading my LSI firmware.
