Re: do i need to give up on this setup

what they said you have a hardware problem. it could be about anything previously mentioned and could also be the power supply being unable to provide a stable 12V for the disks. You should provide the list more specifics on your hw setup, of interest are what kind of SATA/SAS ports you are using and how the disk are cabled in. Note that there are a number of controllers that aren't the most reliable and some of those controllers when something happens will stop responding for all disks connected to it. I have also seen badly designed motherboards have build-in(non-AMD/non-Intel chips) sata ports that don't work under any load that uses more than a single disk at a time, and/or acts badly when given smart commands.

Hi all, Scrubbing ( # echo check > /sys/devices/virtual/block/md1/md/sync_action) is killing my array :( I'm attaching details of the array and disks (bloody wd greens) as well as journalctl errors providing some details about the issue. If you have any pointers on what might be the cause of this as well as any recommendations on how to improve things please let me thank you in advance ... I have backups of the data so happy to move this to a different setup you might recommend (apps will be mostly reading from the array via NFS since most of the content will be media). My suspicion is that a timer service is kicking in and disrupting the scrubbing somehow but can't pinpoint what causes this.It looks like a drive is dropping off the bus and then failing to reidentify, could be bad cabling/controller/PSU, or just a bad drive. You should post "smartctl -a" of all drives as well. -- With respect, Roman-- With respect, Roman
