Description Corey Marthaler 2006-10-19 15:42:09 EDT
Description of problem:
This is a RHEL5 dup of bz 174834.

I reproduced this issue while attempting to create 32 snapshots.

Version-Release number of selected component (if applicable):
Linux taft-04 2.6.18-1.2726.el5 #1 SMP Wed Oct 11 18:53:39 EDT 2006 x86_64
x86_64 x86_64 GNU/Linux
[root@taft-04 ~]# rpm -q lvm2
[root@taft-04 ~]# rpm -q device-mapper
Comment 1 Milan Broz 2006-10-20 03:58:14 EDT
This will be solved by new dm-io implementation, unfortunately there were some
design changes last days and patches are not stable yet. So first possible
include for RHEL 5.1.
