Backup superblock feature is already enabled; nothing to enable
tunefs.ocfs2: Build directory indexed tree failed while enable indexed-dirs
tunefs.ocfs2: Build directory indexed tree failed while building indexed
trees
But, strangely, indexed-dirs is reported as enabled, whereas
discontig-bg, which did not send any warning, is not:
tunefs.ocfs2 -Q "Compat: %M\nIncompat: %H\nRO Compat: %O\n" ${vol}
Compat: backup-super
Incompat: sparse inline-data indexed-dirs
RO Compat: unwritten
On the same volume, I re-run the same command without indexed-dirs. This
was the output:
tunefs.ocfs2 -v --fs-features
backup-super,discontig-bg,sparse,inline-data,unwritten ${vol}
Enabling feature "sparse_files"
Enabling feature "backup_super"
Enabling feature "unwritten_extents"
Enabling feature "inline_data"
Enabling feature "discontig_bg"
Sparse file feature is already enabled; nothing to enable Backup
superblock feature is already enabled; nothing to enable Unwritten
extents feature is already enabled; nothing to enable The inline data
feature is already enabled; nothing to enable
And here's the status report:
Compat: backup-super
Incompat: sparse inline-data indexed-dirs discontig-bg
RO Compat: unwritten
indexed-dirs is still reported even though it was not included in the
last reconfig command, and discontig-bg is finally enabled.
Could someone help me make sense out of this? Was indexed-dirs enabled
the first time around, even though it reported failure? Why was
discontig-bg not enabled the first time, yet it did not report anything
wrong? And then, second attempt, why indexed-dirs remained "enabled"
even though I did not specify it? And is it truly enabled now?
