Re: [LTP] Filesystem Resilience?

[Robert W. <ro...@us...>]

The 'fsstress' test is probably what you are looking for.  I've used it=
 a
few times myself for filesystem testing, and it was able to "successful=
ly"
uncover bugs for me.

Hello.=A0 I'm looking for a good way to test that a filesystem comes ba=
ck
clean after a dirty shutdown.=A0 I'm in the process of testing suitabil=
ity of
network raid with MD and ENBD (http://www.it.uc3m.es/~ptb/nbd/).=A0 The=

filesystem I'm using is JFS, and the raw devices come from LVM.=A0 I'm
filesystem agnostic.=A0 JFS seems fine so I'll use it unless there's a =
good
reason to switch.

Anyway, what I'd like to do is test how well my ENBD-exported device fa=
res
in the event of a dirty shutdown on the primary.=A0 Supposedly, the dat=
a
should be identical on both sides.=A0 From what I've tested so far usin=
g
simple scripts that write and sync data it has appeared to work pretty =
well
-- the network-accessible mirror comes up very nicely.=A0 However, what=
 I
would like to do is put the system under the type of duress that would =
most
likely trigger such things as a corrupted journal or something else whi=
ch
would make it difficult, if not impossible, to recover the filesystem a=
fter
a dirty shutdown.

Is fsstress a good way to do this?=A0 Does anybody on the list use LTP =
for
this type of testing?

Thank you very much for any assistance!
