I have 5 data disks and 1 parity disk. I've been copying some data around on my SnapRAID disks and haven't setup a scheduled sync job yet, so I've been doing it manually. I did one 5 days ago and it completed after 2 days, no issue. Today I went to do a sync after I finished copying data and it keeps saying 'Killed' after "Scanning disk data4..."
SnapRAID status seems to be working fine, I don't see anything that is raising a red flag.
I tried rebooting the computer, didn't work. I tried switching from the backports kernel to the standard, and the killed message came up after "scanning disk data5..." instead of "scanning disk data4..." While syncing, CPU goes between 50 and 74% and Memory Usage goes to around 93%. It seems to peak at 95% CPU right before it stops syncing.
All drives are identical. Nothing else has changed between in the 3 days since my last successful sync other than copying some data from data5 to data4 and data3.
Could it be a RAM issue since it goes up to 93% while trying to sync? OMV shows 5% of 3.69GB while not trying to sync. Looking at the SnapRAID manual, section 7.9, I did the math for RAM and got 2.42GB.
I'll attach some screenshots with more info about my setup.
