[lustre-discuss] MDT mount failing due to unknown param quota

[Brad Merchant]

We have an old IEEL 3.0 system (Lustre ver 2.7.15.3) that we enabled user
and group quotas on several months ago. Today we rebooted the MDS node for
the first time since then and the MDT refuses to mount with

ordered data mode. Opts: user_xattr,errors=remount-ro,no_mbcache

result of communication errors between this node and the MGS, a bad
configuration, or other errors. See the syslog for more information.

Is there a way to disable quota param to get the MDT to mount? Or any other
way to get the MDT to mount?

If it matters the node is currently running e2fsprogs ver 1.42.13.wc4-7
(all targets are ldiskfs)
