Description

I just rebooted our MDS and see the following messages on the console:

Lustre: lstest-MDT0000: Will be in recovery for at least 5:00, or until 265 clients reconnect.

2012-11-26 16:25:09 Lustre: lstest-MDT0000: Recovery over after 1:15, of 265 clients 256 recovered and 9 were evicted.

I haven't looked at the code to determine what the LustreError messages mean, but I wanted to open an issue in the mean time.

First off, these should really be cleaned up and reworked to print something sane that an admin can understand.

Secondly, 9 clients were evicted here, so I'm curious if these eviction are a result of the error messages printed just prior to recovery completion.
