    • Older Parts machine build

      Good afternoon!

      This is the 3rd system I've built for NAS. It is a re-purposed HP SFF PC with an Intel core 2 Quad chip (Q9505), 8 Gb of DDR2 Ram, an 2.5" mechanical HDD 120Gb that holds the OMV system files and 3 1TB mechanical drives. It is running OMV 4 64bit.

      I know this isn't a super efficient build, but I really wanted a machine that had enough SATA ports that i could setup a Raid 5 for hot swapping my cheap used mechanical drives. I mainly use OMV for Samba network shares and a Plex server running through Docker.

      I installed OMV4 yesterday and started the Raid 5 setup. The Raid is still re-syncing, but I've pushed about 600GB into it already (as I am going to replace another OMV system built from a laptop with failing drives). (I copied the files using Samba to the new machine)

      I finally tried setting up notifications for the first time and all of a sudden i'm seeing a ton of them! I installed Glances to try to get an idea of what is going on and I see that i have two warnings/critical alerts, both ongoing:
      Load (2.9)
      CPU_IOWAIT(92.7)

      I compared my performance statistics on my failing OMV setup to this new one and the new one appears to be constantly maxing out Wait-IO (see attachment)

      Is this due to the Raid still re-syncing? There are no users connected and I haven't started using the new system yet so there shouldn't be any resource draw on it yet. Any input would be appreciated!

      I take it you are aware that you can't 'hot swap' drives in a software raid.

      Interesting, you've copied/moved 600GB of data whilst it's re-syncing.

      Hopefully, either that or the CPU is failing.
      Raid is not a backup! Would you go skydiving without a parachute?

      Thanks for the response! I actually didn't think about the Raid being a software Raid... This is the 1st time I've created one, at least i know now!

      I was definitely impatient on adding the data during the re-sync, I guess we'll see what happens after that portion completes. If IO wait is still too high after that I might have to do some testing on the CPU.

      Thanks again!
