Created attachment 348373 [details] fix probe_all() scanning algorithm Description of problem: customer has filesystem on a whole device *and* has a device listed in /proc/partitions that ends in a digit (but it's not a partition). This is tripping up a bug in libblkid:probe_all() where it thinks the whole device to be mounted is a partition of the device listed one line earlier, hence mount fails. This is a bug even though the customer should be mounting a partition, not a whole device. Customer's patch is attached. Customer verified (but not yet SEG verified). Version-Release number of selected component (if applicable): Probably all versions of e2fsprogs, but specifically reported against e2fsprogs-1.39-20.el5 in RHEL5.3. How reproducible: always Steps to Reproduce: 1. set up dm-1 or any other device with device name ending in a digit 2. attempt to mount the whole device listed immediately after dm-1 in /proc/partitions Actual results: mount fails Expected results: mount succeeds
Just out of curiosity, what does /proc/partitions look like?
Scratch that request, probably not needed. I think this upstream commit will fix it: http://git.kernel.org/?p=fs/ext2/e2fsprogs.git;a=commitdiff;h=38361bbbb55735cf0f4ed6d56079c70fb3328036 Can the customer confirm?
Ok, this is most likely 5.5 material, without some sort of big push. Thanks, -Eric
