 Posted: Tue Jun 10, 2025 5:06 pm Post subject: Mount issue with 5.10 jer |
 |
|
Hi Experts, I am trying to mount /dev/sdb1 which is 2Tb HDD , which is formatted by xfs file system on a mount point, however I am getting below error -
| Quote: | # mount /dev/sdb1 /home/internal-2tb-1
mount: /home/internal-2tb-1: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error.
|
| Quote: | ~ # eselect kernel list
Available kernel symlink targets:
[1] linux-5.10.156-gentoo * |
If I go ahead and upgrade the kernel to 6.1.132, and then format the same disk thorough xfs and mount it to a mount point, all works well.
Is there any issues with 5.10 kernel ? I am not sure what exactly am I missing here, please suggest.
Thanks in advance |

| That is a generic mount (command) error. The real message will be in dmesg |

Apologies for the delay grknight, below is the dmesg
| Code: | [Jun12 22:24] XFS (sdb1): Superblock has unknown incompatible features (0x20) enabled.
[ +0.000002] XFS (sdb1): Filesystem cannot be safely mounted by this kernel.
[ +0.000002] XFS (sdb1): SB validate failed with error -22. |

This means that the mkfs.xfs command enabled a feature which older kernels are incompatible with.
For example
bigtime and inobtcount features need kernel 5.10
nrext64 feature needs kernel 5.19
mkfs.xfs can be told not to enable a feature. See its man page

If reformatting is not an option, then yes. |

| I can reformat, please suggest how to go about that - any specific options to be passed along with mkfs.xfs ? |

| Yes, you need to pass the option(s) that tell it not to enable features that are newer than what kernel 5.10 provides. No, I don't have a list of those options at hand. Per grknight's second to last post above, see the manual page for which option(s) you need. Depending on how helpful the manual is, you may need to cross-check that with kernel documentation on when it gained support for particular XFS features. |
