Actually it is me who should be thanking you for not giving up. For me giving up was not an option since that would involve me losing all my data. Thank you again for your time and patience, others would have told me to reinstall my OS or restore my backups. > sudo dnf install > https://download.copr.fedorainfracloud.org/results/ngompa/btrfsprogs-robustimg/fedora-33-x86_64/01873195-btrfs-progs/btrfs-progs-5.9+git20210108.3783313-0.fc33.1.x86_64.rpm > Ok, I finally have some good news and some minor bad news hopefully. Good news first. It worked, I can now mount my BTRFS root file system: # mount -t btrfs /dev/mapper/dm_crypt /mnt/ # ll /mnt # total 0 drwxr-xr-x. 1 root root 0 Jan 12 00:00 before_live_cd_exp dr-xr-xr-x. 1 root root 178 Dec 14 14:58 root dr-xr-xr-x. 1 root root 178 Dec 14 14:58 stable_15_Dec drw-------. 1 root root 22 Dec 11 20:05 swap Now to give you the output of the commands and the minor bad news: 1) btrfs check --repair /dev/mapper/dm_crypt This command actually executed and exited normally, but I could see some errors at the end of the command. Full output of repair command over here: https://drive.google.com/file/d/17EQ5TYJE5a4iwRGTXXj9Hh38btxFBLAJ/view?usp=sharing 2) btrfs check --init-csum-tree /dev/mapper/dm_crypt This is where the minor bad news happens. This command exited with a "Segmentation Fault(Core Dumped)" Full output here: https://drive.google.com/file/d/1IYnLcw-vkZ2UeH0rOZje4kbhzB_tYaKy/view?usp=sharing I have my core dumps set to unlimited: # ulimit -a core file size (blocks, -c) unlimited data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 31030 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 31030 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited But still I was unable to get coredump file as it was not generated: # coredumpctl list btrfs TIME PID UID GID SIG COREFILE EXE Mon 2021-01-11 22:58:18 IST 4337 0 0 11 none /usr/sbin/btrfs Which is weird. All the outputs are compressed using GZIP, let me know if you are unable to download them. The repair command was run before the init-csum-tree command. I have also used your enhanced version of btrfs-progs that you provided: # dnf repoquery --installed btrfs-progs btrfs-progs-0:5.9+git20210108.3783313-0.fc33.1.x86_64 Let me know the next steps ie. Do you need BTRFS logs to diagnose the root cause of the problem ? Thank you once again for your help and perseverance. Couldn't have done it without you. -- Regards, Sreyan Chakravarty _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org
