Distribution: debian-amd64 I'm using JFS quite intensively and it happens that once in 2-3 weeks of uptime the following error appears: ERROR: (device hdb1): DT_GETPAGE: dtree page corrupt Sometimes it is possible to fix the error "on-fly" with fsck.jfs (that found some files cross-linked though), but sometimes attempt to use the volume fixed with fsck.jfs causes more severe problem described in bug 4894 that forces emergency reboot of the system. Of course, there is no reason for the errors to appear. My system is doing just regular file I/O operations, nothing harmful.
Is this the same filesystem as in bug #5073? If it is a case-insensitive filesystem, I'm wondering if that bug may be the cause of the problems. Having bogus dentries in the dcache may possibly lead to some confusion. I'd like to know if I should follow that theory, or whether I could rule it out. Of course, if it happens again after applying the patch for 5073, I can rule it out as well.
Yes, it the same filesystem as in bug 5073. But I've caught bug 5073 just by chance, so I could not say from my experience that the bug 5073 and the current bug are related. Anyway I'm using a patched JFS driver now and we will see if it change anything.
I'm going to assume this is fixed with bug 5073. Please reopen it if you see it again.
