Mount command may fail to mount the file system (3913246)

Last published : Sep 18, 2026
For a file system that was earlier mounted on cluster nodes the first Mount command may fail with the following error:
UX:vxfs mount.vxfs: ERROR: V-3-28543: Cannot be mounted until it has been cleaned by fsck.
Please run "fsck -t vxfs -y /dev/vx/rdsk/<DiskGroup_Name>/<Volume_Name>" before mounting.
Please refer to fsck_vxfs man page for details.
At the same time, the following error message may appear in the system log:
vxfs: msgcnt 463 mesg 021: V-2-21: vx_fs_init - /dev/vx/dsk/\<DiskGroup_Name\>/\<Volume_Name\>
file system validation failure.
These are generic messages and the mount command may fail due to multiple reasons.
Workaround:
  1. Verify all the per node logs to check for a dirty log, if any.
  2. Mount the file system with delayfsck mount option.
Notes:
  • This workaround is applicable only if a dirty log is found.
  • Mounting the file system with the delayfsck mount option is applicable only for disk layout version 11 or later. For disk layout version prior to 11, you must run the full fsck command before the file system is mounted.
  • Even if you have mounted the file system with delayfsck mount option, you must run the full fsck command at a later point in time. You may plan the application downtime and then run the Full fsck command.
