RAID 5 rebuild

  • I had a RAID 5 setup with 3 drives, 1x2TB, 1x3TB and 1x4TB, I removed the 2TB so I could replace it with a larger drive, so I put in a 4TB drive and started a rebuild, but after it finished the storage capacity did not increase.
    Did I mess this up or is there something I have to do to "unlock" the capacity?

    You need to grow the array then grow the filesystem.

    omv 7.0.4-2 sandworm | 64 bit | 6.5 proxmox kernel

    plugins :: omvextrasorg 7.0 | kvm 7.0.10 | compose 7.1.2 | k8s 7.0-6 | cputemp 7.0 | mergerfs 7.0.3

    I don't know what the grow array tab is. Do you mean the Raid Management tab? If you don't see an array in that tab, something is wrong with your array.

    If you manually (from the command line) added the drive and started the rebuild, you will have to manually grow the array.

    The add button grows the array I think. What size does the raid management tab say the array is?

    omv 7.0.4-2 sandworm | 64 bit | 6.5 proxmox kernel

    I don't know what your array name is but the following should grow the array:
    mdadm --grow /dev/md0 --size=max
