After 12 hours the rescue failed and GPT

The error message "chunk tree recovery failed" and "couldn't open RDWR because of unsupported option features" indicates that there are some advanced features in use by your Btrfs filesystem that are not supported by the version of btrfs-progs installed on your system.

Given these challenges, here are alternative steps to try to recover the data:

Step 1: Use btrfs restore Directly

Even if the chunk recovery failed, attempting btrfs restore directly might still work:

• Create a Recovery Directory:

sudo mkdir /volume1/recovery_directory

• Run btrfs restore:

sudo btrfs restore -v /dev/mapper/vg1000-lv /volume1/recovery_directory

Step 2: Mount with Options

Try mounting the filesystem with recovery options to attempt access:

• Mount with Recovery Options:

sudo mount -o ro,recovery,skip_balance /dev/mapper/vg1000-lv /mnt

If the filesystem mounts, copy the data from the mounted directory to another location.

Step 3: Use btrfs check with No Repair

Try running btrfs check without the --repair option to see if it can diagnose issues:

• Run btrfs check:

sudo btrfs check /dev/mapper/vg1000-lv

Step 4: Use btrfs rescue super-recover

Try to recover the superblock:

• Run btrfs rescue super-recover:

sudo btrfs rescue super-recover /dev/mapper/vg1000-lv

• Mount with recovery options:

sudo mount -o ro,recovery,skip_balance /dev/mapper/vg1000-lv /mnt

• Run btrfs check without repair:

sudo btrfs check /dev/mapper/vg1000-lv

• Run btrfs rescue super-recover:

sudo btrfs rescue super-recover /dev/mapper/vg1000-lv

• Consult professional data recovery services if necessary.
