[gpfsug-discuss] Large in doubt on fileset

[Jonathan Buzzard]

I have a DSS-G system running 4.2.3-7, and on Friday afternoon became
aware that there is a very large (at least I have never seen anything
on this scale before) in doubt on a fileset. It has persisted over the
weekend and is sitting at 17.5TB, with the fileset having a 150TB quota
and only 82TB in use.

There is a relatively large 26,500 files in doubt, though there is no
quotas on file numbers for the fileset. This has come down from some
47,500 on Friday when the in doubt was a shade over 18TB.

The largest in doubt I have seen in the past was in the order of a few
hundred GB under very heavy write that went away very quickly after the
writing stopped.

There is no evidence of heavy writing going on in the file system so I
am perplexed as to why the in doubt is remaining so high.

Any thoughts as to what might be going on? 


JAB.
