After setting up Raid1 Mirror on DNS server, now I am planning to go for a Debian upgrade from 10 to 11.

I was able to update the source.list file and perform apt update but when i do apt full-upgrade it fails and when I checked the syslog it shows error as

EXT4-fs error (device md0): ext4_validate_inode_bitmap:100: comm dpkg: corrupt inode bitmap -block_group = 0,inode_bitmap = 1043                                                                                                                                             Aborting journal on device md0-8
EXT4-fs error (device md0) in ext4_free_inode:357: Filesystem failed CRC
Aug  2 12:39:07 localhost kernel: [2141055.420335] EXT4-fs error (device md0) in ext4_evict_inode:351: IO failure

Can someone help in fixing this

  • Obvious first comment is obvious: have you tried to `fsck /dev/md0`? – tsc_chazz Aug 02 '23 at 15:10
  • @tsc_chazz no, i haven't tried that yet....Can it be run on the running system wthout unmounting? – codelearner1029 Aug 03 '23 at 06:20
  • @tsc_chazz i attempted to run fsck /dev/md0 and it asked to reboot which i did and shows this on screen booting from hard disk.. boot failed: not a bootable disk.... no bootable device retry in 1 second – codelearner1029 Aug 03 '23 at 06:57
  • It looks like the upgrade attempt may have been thwarted by a failing disk or by a `grub` install failure. Strong suggestion: find a live disk (probably a bootable USB stick), probably best Debian 10, and use that to try troubleshooting the RAID array and boot filesystem. – tsc_chazz Aug 03 '23 at 07:11
  • @tsc_chazz the sda partition table got deleted ....i selected the boot from sdb and for now the system boots up....how to get back the sda partition? i tried sfdisk and it recovered but it hangs at reboot..may be i am doing wrong or somethng missing – codelearner1029 Aug 03 '23 at 09:11
  • I think at this point we're in new question territory. While I think I know what I'd do, I also know this is an area where I'd be kind of fumbling, it's probably time to hunt someone more knowledgeable in this area. – tsc_chazz Aug 03 '23 at 14:25
  • Guys are you all blind? The harddisks are failing cause of hardware malfunction. OP has probably lost (maybe even all) data. If it was important data, power off your machine immediately and bring your harddisks to a professional data recovery company. Otherwise throw the harddisks into trash and buy new ones. – paladin Aug 03 '23 at 15:05
  • paladin has a fair point, though it may be only sda that's failing. – tsc_chazz Aug 03 '23 at 20:15
