Xsan Filesystem Access [Windows]

Troubleshoot:

| Scenario | Cause | Fix | |----------|-------|-----| | Can see folder but can't open file | Incorrect UNIX execute bit on parent directory | chmod g+x /Volumes/SAN/Project | | Editor says "permission denied" on save | UID mismatch between client and MDC | Sync directory service or re-chown file | | Some users can write, others read-only | Group membership not updated | killall DirectoryService (or dsconfigad refresh) | | ACLs inherited incorrectly | Inherit flag not set | Use chmod -R +a or Xsan Admin’s ACL editor |

Pro Tip: On Xsan, avoid Spotlight indexing on large media folders. Spotlight tries to read every file, creating lock contention and false permission alerts. Disable with: xsan filesystem access

mdutil -E -i off /Volumes/SAN/Media

Check available Xsan volumes:

xsanctl list

Output example:

Volume: "Media_SAN"
   State: Mounted
   Mountpoint: /Volumes/Media_SAN

Manually mount an Xsan volume:

sudo xsanctl mount Media_SAN

Mount at a custom path (not /Volumes):

sudo xsanctl mount Media_SAN /mnt/xsan_media

Unmount safely:

sudo xsanctl unmount Media_SAN

Show detailed volume status:

xsanctl status Media_SAN

List connected clients (from metadata controller only):

sudo xsanctl peers Media_SAN
