[Cluster-devel] [PATCH 00/19] gfs2: misc recovery patch collection

[Bob Peterson <rpeterso@redhat.com>]

This is a collection of patches I've been using to address the myriad
of recovery problems I've found. I'm still finding them, so the battle
is not won yet. I'm not convinced we need all of these but I thought
I'd send them anyway and get feedback. Previously I sent out a version
of the patch "gfs2: Force withdraw to replay journals and wait for it
to finish" that was too big and complex. So I broke it up into four
patches, starting with "move check_journal_clean to util.c for future
use". So those four need to be a set. There aren't many other dependencies
between patches, so the others could probably be taken or rejected
individually.

Bob Peterson (19):
  gfs2: log error reform
  gfs2: Introduce concept of a pending withdraw
  gfs2: Ignore recovery attempts if gfs2 has io error or is withdrawn
  gfs2: move check_journal_clean to util.c for future use
  gfs2: Allow some glocks to be used during withdraw
  gfs2: Make secondary withdrawers wait for first withdrawer
  gfs2: Don't write log headers after file system withdraw
  gfs2: Force withdraw to replay journals and wait for it to finish
  gfs2: Add verbose option to check_journal_clean
  gfs2: Check for log write errors before telling dlm to unlock
  gfs2: Do log_flush in gfs2_ail_empty_gl even if ail list is empty
  gfs2: If the journal isn't live ignore log flushes
  gfs2: Issue revokes more intelligently
  gfs2: Warn when a journal replay overwrites a rgrp with buffers
  gfs2: log which portion of the journal is replayed
  gfs2: Only remove revokes that we've submitted
  gfs2: eliminate tr_num_revoke_rm
  gfs2: don't call go_unlock unless demote is close at hand
  gfs2: clean_journal was setting sd_log_flush_head replaying other journals
