charrington517 Posted March 3 Share Posted March 3 New to Unraid, and still learning. I recently experienced a power outage, and when I brought my server back on line, one of the drives in my Array says that it is unmountable: unsupported or no file system. I ran a smart test on it (short & extended) and it passed without errors. I saw in another post, to stop the array, remove the drive, restart the array, then stop array and add drive back in and start array once more. I tried it, and the drive still shows the same message, and the system also started a data-rebuild (which says it will take over 830 days). Is this rebuild a good thing, like it is fixing the data on the drive? And is the 2 year rebuild time normal? When I have started parity checks previously, they always tell me that it will take 2 to 3 years, is that normal? unraidserver-diagnostics-20240302-1628.zip Quote Link to comment
JorgeB Posted March 3 Share Posted March 3 Rebuilding a drive won't fix an unmountable error, as you have found, which you had asked for help before doing that. It's reporting a long time to rebuild because there are constant ATA errors with parity2, cancel the rebuild, check/replace cables for that disk (power and SATA) and post new diags after array start.

charrington517 Posted March 7 Author Share Posted March 7 Sorry, I have been out of town. I swapped cables and restarted, and still wants to do a rebuild, and still says it will take 2 to 3 years. New diag attached. unraidserver-diagnostics-20240307-1546.zip Quote Link to comment
charrington517 Posted March 7 Author Share Posted March 7 Oh, and my 4 drive still says it is unmountable. how can I remount that drive and keep the files. It is a 14tb drive that has 11tb worth of files. Quote Link to comment
itimpi Posted March 7 Share Posted March 7 The syslog is full of resets on the drive that is ata8 which explains the predicted time. These are normally caused by cabling issues (power or SATA) or power issues. Cannot see the first occurrence to see if it helps Quote Link to comment
charrington517 Posted March 8 Author Share Posted March 8 How can I recover my data from my 4 drive? Everything was fine, then we had an ice storm and lost power for 3 days. When I restarted my server, my 4 drive says Unmountable: unsupported or no file system. How can I get it to remount, and keep all my Data. Again it is a 14tb drive with 11tb of files.

JorgeB Posted March 8 Share Posted March 8 First you need to fix the ATA errors, did you swap both the power and SATA cables for parity2? Quote Link to comment
charrington517 Posted March 15 Author Share Posted March 15 Sorry my responses are so spaced out, but I am very busy and not at home a lot. But I did change both sata and power cables, power cable did have a lose wire! So after I did that and restarted the array, it started another rebuild process and it says it will take only a day. So I think the problem is fixed, but what do I do now to get my 14tb drive working again? Quote Link to comment
