Dear Sir/Madam,
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 :

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!.
