  1. Ok I execute this command 

    Ibtrfs balance start -dusage=75 /mnt/cache

     

    outcome:

     

    Overall:
        Device size:                 931.52GiB
        Device allocated:            931.52GiB
        Device unallocated:            3.02MiB
        Device missing:                  0.00B
        Used:                        593.10GiB
        Free (estimated):            166.57GiB      (min: 166.57GiB)
        Free (statfs, df):           166.57GiB
        Data ratio:                       2.00
        Metadata ratio:                   2.00
        Global reserve:              154.06MiB      (used: 0.00B)
        Multiple profiles:                  no

                      Data      Metadata  System               
    Id Path           RAID1     RAID1     RAID1     Unallocated
    -- -------------- --------- --------- --------- -----------
     1 /dev/sdb1      462.70GiB   3.00GiB  64.00MiB     1.99MiB
     2 /dev/nvme0n1p1 462.70GiB   3.00GiB  64.00MiB     1.02MiB
    -- -------------- --------- --------- --------- -----------
       Total          462.70GiB   3.00GiB  64.00MiB     3.02MiB
       Used           296.12GiB 434.41MiB 112.00KiB    

     

    next steps are :

    1. stop array

    2. remove the device

    3. Start the array 

    4. stop array create you pool 

    5. assign the disk to the new pool 

     

    is it this way ?

     

     

     

    attached the diagnostics.

  2. these are  error that I have in log of cache disk:

    ay 18 06:32:50 Tower kernel: BTRFS error (device sdb1): devid 2 uuid b7a2b6e5-effb-48f3-8fbe-34b212a45d2c is missing
    May 18 06:32:50 Tower kernel: BTRFS error (device sdb1): failed to read the system array: -2
    May 18 06:32:50 Tower kernel: BTRFS error (device sdb1): open_ctree failed
    May 18 06:32:50 Tower root: mount: /mnt/cache: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error.

     

    Do you think that I lost all cache data ?

  3. I did it with ubuntu and it works.

     

    One of the different that I found was this one:  

    before:

     <driver name='qemu' type='raw' cache='writeback'/>

    after:

    <driver name='qemu' type='qcow2' cache='writeback'/> 

     

    Now, I have to do the same with MacOS but in this case, I think that I have to change in the settings -> vm manager  the "Default VM storage path:" with the path of my new SSD.

    Is it in this way ?
