Mount says: mount: /mnt/storage_test: can't read superblock on /dev/sdb2.
Dmesg says:
[ 2021.927627] BTRFS error (device sdb2): parent transid verify failed on logical 91701248 mirror 1 wanted 859 found 815
[ 2021.930881] BTRFS error (device sdb2): parent transid verify failed on logical 91701248 mirror 2 wanted 859 found 815

I tried sudo btrfs check --readonly /dev/sdb2, but it fails with segfault:
parent transid verify failed on 50249728 wanted 848 found 753
parent transid verify failed on 50249728 wanted 848 found 753

fish: Job 1, 'sudo btrfs check --readonly /de…' terminated by signal SIGSEGV (Address boundary error)

I tried sudo btrfs restore /dev/sdb2 /mnt/storage_test, and it copies files to my other disk, but there's too much data, and I can't save it here.
What can I do?
