Hi, I'm trying to track down a problem relating to ext4 problems, in kernel bugzilla 14354. Originally it was thought this was a regression 2.6.31->2.6.32-rc1 regression, but the Aneesh Kumar's report shows a very similar fsck transcript using a 2.6.30-1 kernel (which makes makes it unclear whether this is really a regression or not), and all three reports are tied together by the use of device-mapper. The fsck logs are consistent barriers being disabled. As I recall under some circumstances device mapper silently drops barrier requests --- I thought this was fixed for device mapper in some cases. What's the current status of barrier requests in device mapper? Are they faithfully passed for standard (non-RAID) LVM2 volumes? When was this changed? What about dm-crypto volumes? (One of the reports was with a dm-crypt volume from what I can tell.) Thanks, - Ted -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
