✨ NAME ✨

mounted.ocfs2 β€” bestie, it literally sniffs out every OCFS2 volume chillin' on your system πŸ’… (this is a page from the OCFS2 Manual Pages, section 8, iykyk)


🌸 SYNOPSIS 🌸

mounted.ocfs2 [-d] [-f] [device]

πŸ¦‹ DESCRIPTION πŸ¦‹

okay so mounted.ocfs2 is THE tool for detecting OCFS2 volume(s) hanging out on your system. no cap.

and here's the vibe: if you don't hand it a device, it just goes ahead and scans all the partitions listed in /proc/partitions. main character energy honestly 🫢


πŸ’– OPTIONS πŸ’–

  • -d β€” lists the OCFS2 volumes along with their labels and uuids. it ALSO lists the cluster stack, cluster name and the cluster flags ✨. the possible cluster stacks are o2cb, pcmk and cman. None means it's a local mount or a non-clustered volume (so, not slaying in a cluster, just vibing solo). and a G cluster flag means global-heartbeat for the o2cb cluster stack πŸŽ€
  • -f β€” lists the OCFS2 volumes along with the list of nodes that have mounted the volume. it's giving "who's at the function" πŸ’€

⚠️ NOTES ⚠️

ngl, this part matters. because this utility gathers information without taking any cluster locks, the info listed in the full detect mode could be stale 😭.

and that's only actually a problem for volumes that were not cleanly umounted by the last node. those volumes will show up mounted (as per this utility) on one or more nodes but are in fact not mounted on any node. lowkey a liar, but it's not the tool's fault fr fr.

such volumes are awaiting slot-recovery, which is auto-performed on the next mount (or file system check). so like, it fixes itself, bestie 🌈

🌟 EXAMPLES 🌟

to view the list of OCFS2 volumes, do:

# mounted.ocfs2 -d
Device     Stack  Cluster     F  UUID                              Label
/dev/sdc1  None                  23878C320CF3478095D1318CB5C99EED  localmount
/dev/sdd1  o2cb   webcluster  G  8AB016CD59FC4327A2CDAB69F08518E3  webvol
/dev/sdg1  o2cb   webcluster  G  77D95EF51C0149D2823674FCC162CF8B  logsvol
/dev/sdh1  o2cb   webcluster  G  BBA1DBD0F73F449384CE75197D9B7098  scratch
/dev/sdk1  o2cb   webcluster  G  DCDA2845177F4D59A0F2DCD8DE507CC3  hb1

to view the list of nodes that have potentially (see notes πŸ‘€) mounted the OCFS2 volumes, do:

# mounted.ocfs2 -f
Device     Stack  Cluster     F  Nodes
/dev/sdc1  None
/dev/sdd1  o2cb   webcluster  G  node1, node3, node10
/dev/sdg1  o2cb   webcluster  G  node1, node3, node10
/dev/sdh1  o2cb   webcluster  G  Not mounted
/dev/sdk1  o2cb   webcluster  G  node1, node3, node10

see that Not mounted? yeah. icon behavior actually πŸ‘‘
