Subject: [PATCH 0/3] xfs: add the ability to flag a fs for repair
Date: Mon, 30 Nov 2020 19:37:19 -0800 [thread overview]
Message-ID: <160679383892.447856.12907477074923729733.stgit@magnolia> (raw)
Hi all,
This "new feature" adds a new incompat feature flag so that we can force
a sysadmin to run xfs_repair on a filesystem before mounting. The
intent for this code is to make it so that one can use xfs_db to upgrade
a filesystem to support new V5 features (e.g. y2038 or inode btree
counters). Because some upgrades may require xfs_repair to fix or add
things before the filesystem goes back into use, this is the means for
xfs_db to force that to happen.
Note: xfs_admin will automatically run repair when required, so
sysadmins won't have to issue the repair command directly.
If you're going to start using this mess, you probably ought to just
pull from my git trees, which are linked below.
This is an extraordinary way to destroy everything. Enjoy!
Comments and questions are, as always, welcome.
