Package: kpartx Version: 0.4.9+git0.4dfdaf2b-7~deb7u1 Severity: critical
When updating kpartx from 0.4.9+git0.4dfdaf2b-6 to 0.4.9+git0.4dfdaf2b-7~deb7u1, SAN volumes cannot be mounted anymore. The SAN volumes are
provided using multipath-tools. $ cat /etc/debian_version 7.2 $ uname -a Linux HOSTNAME 3.2.0-4-amd64 #1 SMP Debian 3.2.51-1 x86_64 GNU/Linux $ multipath -ll HOSTNAME-db (VOLUMEID) dm-0 IBM,2145 size=15G features='1 queue_if_no_path' hwhandler='0' wp=rw |-+- policy='round-robin 0' prio=25 status=active | |- 0:0:0:0 sda 8:0 active ready running | `- 1:0:1:0 sdj 8:144 active ready running `-+- policy='round-robin 0' prio=5 status=enabled |- 1:0:0:0 sdd 8:48 active ready running `- 0:0:1:0 sdg 8:96 active ready running After performing the package update, a system reboot has been performed, because the kernel had to be updated, too. Then, the following syslog entries have been found:Oct 14 11:02:14 HOSTNAME kernel: [ 19.092117] device-mapper: table: 254:7: multipath: error getting device Oct 14 11:02:14 HOSTNAME kernel: [ 19.092206] device-mapper: ioctl: error adding target to table
$ mount /var/lib/mysql device mapper mount: /dev/sdj1 already mounted or /var/lib/mysql busy The volume has not been mounted already (checked in /proc/mounts). $ ls -l /dev/mapper total 0 crw------T 1 root root 10, 236 Oct 14 11:02 control lrwxrwxrwx 1 root root 7 Oct 14 11:02 HOSTNAME-db -> ../dm-0 Here, the partition entry "HOSTNAME-db-part1" is missing. Workaround: - downgrading kpartx to 0.4.9+git0.4dfdaf2b-6 - downgrading multipath-tools to 0.4.9+git0.4dfdaf2b-6 (both the packages are directly correlated) - set kpartx and multipath-tools to "hold" to prevent futher updates
