ReadyNAS crash on Balance task
Hi guys,
A couple of times now my ReadyNAS Pro 6 has completely locked up during a BTRFS Balance task. It's only recently been set up, so I've never actually had a balance go to full completion...
Ah, good to know. I only do them once a month as a "good measure" because I know how BTRFS can be when it doesn't get the necessary TLC.
Great point about the disks, I'm aware of one that had ATA errors but the number hasn't changed (sitting on 10 currently). Is that a cause for concern? I've now found 2 more with ATA errors though, sitting on a count of 1 and 2. All the other counters are sitting on 0 for all disks:
Reallocated Sectors: 0
Reallocation Events: 0
Spin Retry Count: 0
Current Pending Sector Count: 0
Uncorrectable Sector Count: 0
Once the resync completes I'll disconnect the LUNs and try a scrub, will report back here on how it goes.
Thanks!
I've seen the readysasd task jump to 100% during a scrub on my 516, effectively locking up the UI. Maybe a balance could do it as well, especially if it was the first (and probably longer). If you have SSH and itr should happen again, try going in that way and use TOP to see if something's taking all the CPU power.
I've started the scrub now, I'll report back on the findings from that.

I thought that may be the case and wanted to check top, so I tried a couple of things:
- Pinging the NAS (times out)
-SSH (times out)
-Single quick-press of the power button (usually changes the LCD to display a warning that a second press will power off the NAS, but the display stayed as-is).
All those things indicated to me that the OS had locked up
