Hi all,
I agree, there should be no special cases for what should be a routine
filesystem expansion. UFS can be grown any time, not matter what the
filesystem internals happen to be at the time of 100% fs full bonanza.
Even with sufficient monitoring in place, it's a bit hard to pickup
and prevent fastly growing filesystem usage from hitting the 100%
limit and stopping an application component. And it's especially
interesting seeing lots of SAN storage free on the DG only to realise
none of it can be used for growing the filesystem online.
Scott,
many thanks for the investigation into this. Seems we're not the only
ones facing this situation. We've grown the fs via other means
(application process freed up a bit of space eventually from one of
the files it was writing to, took a few hours).
Here's what we were able to do after growing the actual volume & above
process freeing the space up:

We've got a case open with Symantec, I'll email it separately... if I
can still find it that is...
