Hi all
I have about 400TB of storage running dht on ZFS and want to change the
way the extended attributes are stored, assuming it's safe to do this in
ZFS version 0.6.2? I discovered by experimentation that if I remove the
attributes on the server, Gluster will remake them when a file is first
accessed. So the question is, would it be safe to simply delete all the
attributes from all files and just let Gluster remake them?
GlusterFS does maintain state in extended attributes and manually
altering this state information has to be done very carefully.Removing
extended attributes for directories is not recommended as this can
potentially result in gfid split brains.
As far as files go in a distributed cluster (with no replication), the
gfid attribute can be removed and it gets re-created on access. What
other attributes do you intend removing?
