Hello,
with kernel 2.6.22.10 checking a raid1 or rebuilding ist does not work on
one of our machines. After a short time the rebuild/check does not make
progress any more . Processes which then access the filesystems on those
raids are blocked.
Nothing gets logged. Access to other filesystems works fine.
If we boot 2.6.17.10 (the kernel we used befor upgrading to 2.6.22) the
raids the check/rebuild is done without any problems.
Sounds like a driver problem.
Your symptoms are completely consistent with a request being submitted
to the underlying device, and that request never completing.
What controller runs your drives for you. You should probably report
the problem to the relevant maintainer.
3ware Inc 9xxx-series SATA-RAID.
There are no problems with normal operation. And when those raids stop to work
all other disks on the same controller still work.
And I don't see problems when reading from several disk in parallel.
But this doesn't mean its not the driver, of course.
Do you compile your own kernels?
Yes.
Would you be comfortable using git
bisect to narrow down exactly which change breaks things? It should
take more than a dozen or so tests.
Yes. Its a little bit difficult as I can only test kernels in the night and on
weekend.
First I have to see how to use git to get the repository and how to do git
bisect.
