TacoBlackHole Posted December 11, 2019 Share Posted December 11, 2019 (edited) tower-diagnostics-20191211-1608.zip A data drive suddenly disappeared and I don't know why. I have 5 drives: 8gb parity 240gb SSD cache 6TB data 4TB data 8TB data The 6TB drive, after a reboot, showed up in "unassigned devices." With the array in maintenance mode, I can mount the drive and see the data on it. If I mount and add it to the array, the array thinks it's a new device and will erase and rebuild the missing data (that's not missing). 1. Why would this suddenly happen? 2. How can I add it back to the array without losing data? Edited December 11, 2019 by TacoBlackHole Added diagnostics Quote Link to comment
trurl Posted December 12, 2019 Share Posted December 12, 2019 Do you have Syslog Server setup so you can get us the logs from before the reboot? Was that disk recently added/replaced? Quote Link to comment

Was that disk recently added/replaced? Ok, I think I have an idea what happened. I have this seagate 6TB drive. I moved some drives around in the case to put them on an SAS HBA card. But the spot in the case was short on power plugs so I used an SATA splitter. I starved one of the drives of power and then it just crapped errors everywhere. Unfortunately I think it might have zapped some of the parity drive too. Now I can't get the array to stop to see if I can plop the drive back in though I've moved some power plugs around. The whole thing is kind of fubar now, but I'm currently copying the emulated contents to a known good drive to salvage what I can before going any further.
