Symptom & Impact

Mount fails with ‘mount: 0506-324’ and fsck reports JFS2 superblock issues.

Environment & Reproduction

Power loss or storage outage corrupted a JFS2 filesystem.

Root Cause Analysis

Logredo could not replay the JFS2 log cleanly at mount time.

Quick Triage

Identify the LV and FS with lsfs and lsvg -l rootvg.

Step-by-Step Diagnosis

Unmount any holder with fuser -kxuc /mountpoint and confirm clean.

Solution – Primary Fix

Run fsck -y /dev/LVNAME (unmounted) to attempt automatic repair.

Solution – Alternative Approaches

Restore the filesystem from backup with restore -xf if fsck cannot repair.

Verification & Acceptance Criteria

mount /mountpoint succeeds and applications read/write expected data.

Rollback Plan

Re-mount read-only with mount -r if integrity is still uncertain.

Prevention & Hardening

Keep JFS2 with inline log and schedule regular fsck windows.

Related Errors & Cross-Refs

Pairs with J2_LOGREDO_FAIL and LVM_SA_QUORCLOSE errpt entries.
