SomeWhatLost Posted July 22, 2016 Share Posted July 22, 2016 and how could my parity be valid if the parity drive is off line? Parity is valid Last checked on Sun 03 Jul 2016 08:01:13 AM CDT (nineteen days ago), finding 0 errors. Duration: 16 hours, 1 minute, 47 seconds. Average speed: 104.0 MB/sec and does 140,724,705,158,671 seem like a lot of reads to anyone? version 6.2.0-beta23 if that matters. Quote Link to comment
trurl Posted July 23, 2016 Share Posted July 23, 2016 Post diagnostics. What do I do if I get a red X next to a hard disk? Quote Link to comment
SomeWhatLost Posted July 23, 2016 Author Share Posted July 23, 2016 the diags just say that the drive went off line.... Smartctl open device: /dev/sdh failed: No such device not much to go by... Quote Link to comment
SpaceInvaderOne Posted July 23, 2016 Share Posted July 23, 2016 the diags just say that the drive went off line.... Smartctl open device: /dev/sdh failed: No such device not much to go by... check that you sata and power cables are all good. I had a problem with a cable before that caused a similar issue.

SomeWhatLost Posted July 23, 2016 Author Share Posted July 23, 2016 there was no smart data... all there is was the "Smartctl open device: /dev/sdh failed: No such device" as for cables, it is a supermicro SAS2 backplane, if it were a cable issue, all drives would be having an issue... as a side note, I seem to be having some issue with the cache drive... basically, I am doing a batch converting of all my VIDEO_TS to MKV (seemed like a good time clean things up a bit, join the modern era, etc... most of my VIDEO_TS VOB's were split up to get past the old XP or WIN95 file size limit, lots of files to keep track of, lots of wasted space...) anyway, it has been running 24/7, seems every once in a while it tries to write to a file while the cache is trying to move that file and it screws stuff up/batch process crashes... wonder if that could also be causing parity unhappiness? towerb-smart-20160722-1725.zip Quote Link to comment
trurl Posted July 23, 2016 Share Posted July 23, 2016 ... wonder if that could also be causing parity unhappiness? No. It failed a write attempt. This is a hardware issue of some kind. Did you take a look at the wiki I linked? Quote Link to comment
SomeWhatLost Posted July 25, 2016 Author Share Posted July 25, 2016 yea, I looked at the wiki. I mounted the drive in UD, it needed to be formatted (XFS) ran a smart test and it cam back pack perfect, wrote and deleted a couple large files to it, that worked perfectly too... I tried to do a preclear, but it came back as "Drive Busy", which then reminded me, whats up with preclear? it always say drive busy with all my drives, I did a quick search, and tried the preclear gui beta thing, that didn't help either... so anyway, I set the drive back as parity, it rebuilt and seems to be fine now.

Parity drive doesn't have a filesystem, so it is supposed to be unformatted. Also, preclear will not clear a drive it thinks is part of your array, so unless you somehow made it forget your parity drive (new config) it will not preclear it. Sounds like you got it sorted though. Quote Link to comment
00b5 Posted July 25, 2016 Share Posted July 25, 2016 Might be good to get a full smart report from it now. It fell out of the array somehow, and unless you went in and checked all the physical connections, you should try to figure out what happened. BTW, 2 months is not too long for a hdd to start failing. You expect it to last at least its warranty period and then some, but its a spinning mechanical device, so it could do anything.
