I playing around with F37 Server, Cockpit, btrfs mirror under vbox:
created a mirror with:
mkfs.btrfs -L MyMirror -m raid1 -d raid1 /dev/sdb /dev/sdc
fetched the UUID with:
btrfs fi show
setup the /etc/fstab:
UUID=<MyMirror's-uuid> /home/DATA btrfs device=/dev/sdb,
device=/dev/sdc,compress=zstd:1 0 0
or
UUID=<my-uuid-here> /home/DATA btrfs compress=zstd:1 0 0
rebooted
when I look at cockpit's "Storage" I see both disks are mounted, but also at
the most right side a exclamation mark for /dev/sdc.
clicking down to the /dev/sdc:
=> "The filesystem is not mounted"
=> "Inconstistent filesystem mount"
=> "The filesystem is currently not mounted but will be mounted on the next
boot"
Is it a shortcoming of cockpit ?
cause no hints in dmesg and the mirror is usable e.g. fillable via smbshare and both disk
do have the same fill level.
