stor44 Posted November 15, 2018 Share Posted November 15, 2018 (edited) Hello. I'm seeing two alerts in my normally stable unraid system. 1st one says "Warning [TOWER] - Cache pool BTRFS missing device (disk serial #)." 2nd alert says "Warning [TOWER] - array has errors. Array has 6 disks with errors." Log files now attached. I have a pair of WD Blue SSD drives for my cache pool, I'm guessing one of them has failed (or has a bad cable, etc)? Thanks for any advice. tower-diagnostics-20181115-1329.zip UPDATE: Got home and shutdown unRAID, as there didn't seem to be anything else to try. Checked the SSD cables. Booted it up again, and now everything is fine...array is good, no cache problems. False alarm I guess. Edited November 16, 2018 by stor44 (SOLVED) Quote Link to comment
JorgeB Posted November 16, 2018 Share Posted November 16, 2018 One of your cache devices dropped offline, you should check/replace cables and at least run a scrub Quote Link to comment
stor44 Posted November 16, 2018 Author Share Posted November 16, 2018 Thanks johnnie. I’m running a parity check right now, 2.5hrs to go. It says 2 sync errors so far. Quote Link to comment
stor44 Posted November 17, 2018 Author Share Posted November 17, 2018 Just an update to close this thread off. 2nd parity check finished, finding 2 sync errors. It was a non-correcting parity check, so I ran another one with write corrections checked, and it has now finished and corrected the two errors. All good now. Quote Link to comment
JorgeB Posted November 17, 2018 Share Posted November 17, 2018 The problem was caused when the HBA stopped responding, you're like the third user I've seen this happening to recently, all using very old LSI firmware: Nov 12 06:11:03 Tower kernel: mpt2sas_cm0: LSISAS2008: FWVersion(07.15.08.00), ChipRevision(0x03), BiosVersion(00.00.00.00) You should update to latest, currently 20.00.07.00 1 Quote Link to comment
stor44 Posted November 17, 2018 Author Share Posted November 17, 2018 Thanks so much john, I found Fireball3's instructions how to do that, and have now updated the HBA firmware: Nov 17 12:18:59 Tower kernel: mpt2sas_cm0: LSISAS2008: FWVersion(20.00.07.00), ChipRevision(0x03), BiosVersion(00.00.00.00) Quote Link to comment
