June 10, 201115 yr And I had my server on, with no battery back up. Turned it on today, and it's currently doing a parity check. Every time I've done a parity check, there seems to be errors. Is this common? It appears to correct them all, but, just wondering... So I guess when the server shuts down, any modifications since the last start up are lost, correct? Since the booted FS is in memory, it doesn't get a chance to write back to the flash drive. Now, I'd imagine that's fairly trivial--so long as it hasn't been a weeks+ worth a modifications. Are there any other reasons why it may be dangerous to keep unRAID off of a UPS when the power flickers? (was literally a flicker--off for no more than 5 seconds).

Yes, if the power flickers one of those times and you don't have a surge protector on it it could fry some of your hardware. If it is not on a UPS the unclean shutdown could corrupt files, folders, entire disks, and/or the flash drive.
