It seems unlikely that fsck is going to help. The BUG_ON in question appears to be: BUG_ON(inode->i_data.nrexceptional); This is an in-memory accounting variable which seems to be related to tracking DAX and shadow page entries --- and it seems very unlikely to be the sort of thing triggered by an on-disk corruption. Do you have a reliable repro for this? If so, the next step would be to bisect... - Ted ^ permalink raw reply [flat|nested] 2+ messages in thread

So I ... bcc them too? Nah, I bcc'ed them so that people on those lists would understand that I had dropped them from thread because it probably isn't appropriate to include them on the thread. > > Do you have a reliable repro for this?

OK, let's see if anyone else reports a similar failure. - Ted ^ permalink raw reply [flat|nested] 2+ messages in thread
