OK, so it should work as expected.
The story was this.
After fixing the RAID-5 superblock problem, we
wanted to see if the filesystem was still OK.
So we started the RAID in r/o mode (so to avoid
any possible further damage from mount) and then
mounted the filesystem (actually, now that I
think of it, there was an LVM layer in the middle).
This mount caused a kernel error report (I do
not know if BUG() or else).
Is there any explanation for that?
Thanks,
bye,
