Package: lvm2 Version: 2.02.39-8 Severity: grave File: /sbin/lvcreate Justification: renders package unusable
I have a backup script which creates and destroys LVM snapshots ever day. A few days after upgrading to device mapper 2:1.02.48-3, the backup lvcreate began to fail with the following message: | device-mapper: create ioctl failed: Device or resource busy | Aborting. Failed to activate snapshot exception store. This is caused by the system limit on the number of semaphore arrays being reached. It seems that lvcreate/lvremove operations each create a number of semarphore arrays, but to not remove them before exiting: $ sudo ipcs -s | wc -l 121 $ sudo lvcreate -s -L 1G -n blah thoth/home /dev/dm-8: open failed: No such device or address Logical volume "blah" created $ sudo ipcs -s | wc -l 124 $ sudo lvremove thoth/blah Do you really want to remove active logical volume "blah"?
