Thanks for the prompt reply :)
Firstly many thanks for the brilliant work being put into reiser4. Been using reiser4 for about 10 days or so on two software raid6 devices containing lots of imap mail directories. One partition has about 55GB mail in total, the other only about 4GB. So far so good with no major problems until this morning, when the Oops below (scroll down to bottom of mail) happened. The system continued functioning with no apparent data loss except load average rose to 24 within about 30 secs of the Oops and continued to rise steadily until system became unresponsive after 3-4 hrs with load average at 1189. This is a Centos 5.5 64 bit box with vanilla kernel.org 188.8.131.52 and reiser4-for-2.6.37.patch I have both the raid md devices mounted as reiser4 with noatime,nodiratime I notice this Oops reported here and Edward's patch to address the problem: http://www.spinics.net/lists/reiserfs-devel/msg02648.html Searching through reiser4-for-2.6.37.patch it seems that patch is in there, but I still got the Oops.This is another problem.
Aaah yes you're right, I just saw jbd2__journal_start and ext4_journal_start_sb in both Oops but didn't look further.
Similarly to the previous case, this box is using ext4 for all the other filesystems. If another patch is not possible in the near future would downgrading the other filesystems to ext3 be a temporary workaround for this issue?I have attached a temporal workaround, it should help. Note, that I didn't test this patch: I'll be able to do it at the end of weekends.
Many thanks, I will apply it tonight and report back. Eddie -- To unsubscribe from this list: send the line "unsubscribe reiserfs-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
