Strats Posted February 14, 2020 Share Posted February 14, 2020 I am on 6.8.2. I am not able to write to my cache drive it seems. It is a 480 GB SSD and is only about half full. I have attached my diagnostics file for review. If someone could review the diagnostics and provide a suggestion or two for me to pursue that would be appreciated. tower-diagnostics-20200214-1713.zip Quote Link to comment
JorgeB Posted February 15, 2020 Share Posted February 15, 2020 There's a hardware problem with the cache device resulting in read errors: Feb 14 17:13:20 Tower kernel: ata8.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 Feb 14 17:13:20 Tower kernel: ata8.00: failed command: READ DMA EXT Feb 14 17:13:20 Tower kernel: ata8.00: cmd 25/00:20:20:82:35/00:00:1c:00:00/e0 tag 9 dma 16384 in Feb 14 17:13:20 Tower kernel: res 51/40:00:00:00:00/00:00:00:00:00/e0 Emask 0x9 (media error) Feb 14 17:13:20 Tower kernel: ata8.00: status: { DRDY ERR } Feb 14 17:13:20 Tower kernel: ata8.00: error: { UNC } Feb 14 17:13:20 Tower kernel: ata8.00: configured for UDMA/133 Feb 14 17:13:20 Tower kernel: sd 7:0:1:0: [sdc] tag#85 UNKNOWN(0x2003) Result: hostbyte=0x00 driverbyte=0x08 Feb 14 17:13:20 Tower kernel: sd 7:0:1:0: [sdc] tag#85 Sense Key : 0x3 [current] Feb 14 17:13:20 Tower kernel: sd 7:0:1:0: [sdc] tag#85 ASC=0x11 ASCQ=0x4 Feb 14 17:13:20 Tower kernel: sd 7:0:1:0: [sdc] tag#85 CDB: opcode=0x28 28 00 1c 35 82 20 00 00 20 00 Feb 14 17:13:20 Tower kernel: print_req_error: I/O error, dev sdc, sector 473268768 Feb 14 17:13:20 Tower kernel: BTRFS error (device sdc1): bdev /dev/sdc1 errs: wr 0, rd 1327, flush 0, corrupt 0, gen 0 This is corrupting the filesystem, they are logged more like an actual SSD problem but try a swapping cables and controller first and see if these go away, if not you'll need to replace it, also will likely need to re-format pool to fix current corruption.

Strats Posted February 15, 2020 Author Share Posted February 15, 2020 Thanks, I have been able to recover most of the appdata from this drive. I will replace it with another drive and see what happens. This one has gotten hot recently, maybe caused some problems as a result. Quote Link to comment
