SSD Cache failing?


Recommended Posts

I have a cache pool made up of two SSD 480gb SSD drives in a raid 1. Over the last few days I have noticed that my trim cron job has errored. Just looked at the server and the log file is nearly full. It is full of entries such as :

 

 

Sep 6 21:01:19 PCServer kernel: sd 10:0:0:0: [sdi] tag#28 UNKNOWN(0x2003) Result: hostbyte=0x04 driverbyte=0x00 cmd_age=0s Sep 6 21:01:19 PCServer kernel: sd 10:0:0:0: [sdi] tag#28 CDB: opcode=0x2a 2a 00 11 52 0f 00 00 00 80 00 Sep 6 21:01:19 PCServer kernel: blk_update_request: I/O error, dev sdi, sector 290590464 op 0x1:(WRITE) flags 0x1800 phys_seg 16 prio class 0 Sep 6 21:01:19 PCServer kernel: BTRFS warning (device sdf1): lost page write due to IO error on /dev/sdi1 (-5) Sep 6 21:01:19 PCServer kernel: BTRFS warning (device sdf1): lost page write due to IO error on /dev/sdi1 (-5) Sep 6 21:01:19 PCServer kernel: BTRFS warning (device sdf1): lost page write due to IO error on /dev/sdi1 (-5) Sep 6 21:01:19 PCServer kernel: BTRFS error (device sdf1): error writing primary super block to device 2 Sep 6 21:01:24 PCServer kernel: scsi_io_completion_action: 53 callbacks suppressed Sep 6 21:01:24 PCServer kernel: sd 10:0:0:0: [sdi] tag#4 UNKNOWN(0x2003) Result: hostbyte=0x04 driverbyte=0x00 cmd_age=0s Sep 6 21:01:24 PCServer kernel: sd 10:0:0:0: [sdi] tag#4 CDB: opcode=0x2a 2a 00 00 12 9c 88 00 00 18 00 Sep 6 21:01:24 PCServer kernel: print_req_error: 54 callbacks suppressed Sep 6 21:01:24 PCServer kernel: blk_update_request: I/O error, dev sdi, sector 1219720 op 0x1:(WRITE) flags 0x0 phys_seg 3 prio class 0

 

 

I have a feeling that the second cache drive is failing? I can not also undertake a smart report.

 

I would say the drive is failing or has failed? Unraid is not showing any errors in the 'Main tab'. The drive in question has a lot more reads and writes.

 

As part of a cache pool, I should be able to stop the array. Unassign the drive, power down the server, install new SSD, assign it and it should rebuild?

 

Any help or advice is greatly appreciated.
