Agreed. I lost my raid array moving from 0710 to 0810.
I now have a dedicated NAS backup (not mounted by lmce) so it isn't spinning 24/7. Still using software raid but thinking of reverting to single disks. My raid disks have been spinning for months without a rest.
Best solution IMHO would be a rsync incremental overnight backup of the lmce media drive(s) to the NAS. Just need a NAS that supports rsync.
What did you do with your raid while moving from 0710 to 0810? I have moved mine and didn't lost a bit of data. I also have LVM and LUKS encryption on top of RAID-5.
Also added a new disk recently and while growing raid-5 field power went off! I thought that data was gone, but after consulting with few linux gurus I got RAID to rebuild and grow without any issues.
@posde The wear on disk is never the same, here probability and chaos theory comes in place. It is statistically almost impossible for all drives to fail at same hour or day, let alone AT THE SAME TIME. Complete PR bullshit if you ask me.
My strategy is to change drives every 3 years with new ones, no matter if they had a failure or not.
