I get this error whenever I create a bunch of snapshots. I have 36 filesystems in my vg. If I walk through them creating a snapshot on each one, the last 4 fail. They fail with the below error. I did the order backwards and got the same results so its not dependant on the lv I'm snapshotting, it appears to be dependant upon the number of snapshots I'm creating. /usr/sbin/lvcreate -L 1G -p r -s -n save_perpet2-20060619161740 /dev/svg/save_perpet2lv device-mapper: reload ioctl failed: Cannot allocate memory Failed to suspend origin save_perpet2lv It creates the snapshot devices in /dev/mapper. ls -l /dev/mapper/svg-save_perpet2--20060619161740* brw-rw---- 1 root disk 253, 159 Jun 20 15:19 /dev/mapper/svg-save_perpet2--20060619161740 brw-rw---- 1 root disk 253, 158 Jun 20 15:19 /dev/mapper/svg-save_perpet2--20060619161740-cow but it doesn't create any devices in /dev/svg. It also is available to query with lvdisplay. lvdisplay /dev/svg/save_perpet2-20060619161740 --- Logical volume --- LV Name /dev/svg/save_perpet2-20060619161740 VG Name svg LV UUID oP2nDj-aa7p-dS3Q-4VdH-gk8r-x5C8-Akg78K LV Write Access read/write LV Status available # open 0 LV Size 1.00 GB Current LE 256 Segments 1 Allocation inherit Read ahead sectors 0 Block device 253:159 I can't do anything with that volume other than remove it though. I'm running RHEL 4 U 3 with the beta hugemem kernel installed. I installed the beta kernel as the request of redhat support. device-mapper-1.02.02-3.0.RHEL4 udev-039-10.12.EL4 kernel-hugemem-2.6.9-39.EL Any insight would be appreciated. _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
