I feel like I'm trying to hit the elusive mole on the head! Every time I
fix something more weirdness pops up!
Background: Upgrade from 1.8.9 to 2.10
Test upgrades in the lab worked however I broke index values in the real
upgrade, started an lfsck and only after it had run for some time got to
fixing the index values. After much seemingly random weirdness with
individual OSTs not seeming to heed writeconf, hanging on mount etc. I
did get the whole system to come up with errors in the logs that I have
posted a separate message about.
At the moment:
I can ls to the second level in the tree.
I can cat the few files at this level. Most actual data is deeper in the
I can lfs find and lfs getstripe all files seemingly reliably.
An ls on a directory lower in the tree e.g.
strace ls /exports/terra/data/gfs
Likewise 'cat' on some arbitrary text file fails while 'strace cat' on
the same file works!
Apart from the name of a good psych facility does anyone have advice on
how to proceed?
We are pretty desperate here!
