Reply-To: LVM general discussion and development List-Id: LVM general discussion and development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , List-Id: Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: Linux LVM discussion I'm running x86 Linux 2.6.9, with the 2.6.9-udm patches, lvm2-2.00.02, device-mapper-1.00.17. Occasionally, when I try creating a snapshot, I get the following out of lvcreate: device-mapper ioctl cmd 9 failed: Cannot allocate memory Couldn't load device 'shadowdb-homesnap'. Problem reactivating origin home device-mapper ioctl cmd 6 failed: Invalid argument Couldn't resume device 'shadowdb-homesnap' Aborting. Failed to activate snapshot exception store. Remove new LV and retry. There is also an accompanied kernel message that I'll send once I can get this to happen again while I'm at the machine. Is this problem known? Should I try building a newer version of the lvm2 utilities, and device-mapper library? Any pointers? Thanks, Dave Brown
