Package: btrfs-progs
Version: 7.0-1+b1
Severity: normal
Hi,
I have an interesting which was triggered by fsarchiver, a tool to
backup and restore file systems.
When fsarchiver restores a file system, it tries to use the same UUID as
before (the UUID is recorded in the archive). With btrfs, this fails
though.
You can reproduce the issue easily:
# truncate -s 2G /tmp/image.img
# DEVICE=$(losetup -fP /tmp/image.img --show)
# mkfs.btrfs -f -q -L Test -U 'f42896b1-3815-4e1e-a01a-9261c5bab6f8' $DEVICE
< now run it a second time>
# mkfs.btrfs -f -q -L Test -U 'f42896b1-3815-4e1e-a01a-9261c5bab6f8' $DEVICE
ERROR: cannot open device '/dev/nvme0n1p12': Device or resource busy
ERROR: open ctree failed
< interestingly, running it once again then works again >
# mkfs.btrfs -f -q -L Test -U 'f42896b1-3815-4e1e-a01a-9261c5bab6f8' $DEVICE
ERROR: superblock magic doesn't match
Regards,
Michael
