My OMV nas has worked really well since i upgraded my hardware.
Now one of the raid systems is having some kind of issue : /dev/md127 which consists of four 3tb Toshiba disks.
any file activity is slow & unresponsive on the filesystem, and if for example a copy a file from a folder on the md127 filesystem to another folder on md127.
i get these kind of errors in my /var/log/messages :
May 25 14:50:54 pgnas kernel: [ 4572.606159] ata15: SATA link up 1.5 Gbps (SStatus 113 SControl 310)May 25 14:50:56 pgnas kernel: [ 4574.650731] ata16: SATA link up 1.5 Gbps (SStatus 113 SControl 310)May 25 14:51:27 pgnas kernel: [ 4605.370682] ata17: SATA link up 3.0 Gbps (SStatus 123 SControl 320)May 25 14:51:57 pgnas kernel: [ 4636.082573] ata18: SATA link up 3.0 Gbps (SStatus 123 SControl 310)May 25 14:52:28 pgnas kernel: [ 4666.826196] ata16: SATA link up 1.5 Gbps (SStatus 113 SControl 310)
Which is all 4 drives in md127.
i have swapped out some of the sata cables, but the same errors on the disks that i have swapped data cables on keep appearing.
i have another raid md126 , attached to the same sata controller, that i do not have any issues with.
any help on this is very appreciated!.
