Re: Cache pressure fail

[Gregory Farnum <greg@xxxxxxxxxxx>]

Did you upgrade your clients along with the MDS? This warning indicates the MDS asked the clients to boot some inboxes out of cache and they have taken too long to do so.
It might also just mean that you're actively using more inodes at any given time than your MDS is configured to keep in memory.
