Problem
RHEL 7.2 or above or CentOS reboots or freezes during backup job.
Error Message
Large amount of following messages are generated during backup:
"kernel: 3>Failed to get the sSD info"
Cause
In RHEL 7.2 and above or CentOS a new file system probe rule is added. Due to this new rule VSRL snapshot devices are being probed which is interfering with the VSRL backups.
Solution
To overcome this undesired behavior, please update the udev rule so that it won’t probe VSRL specific device :
- cp -p /usr/lib/udev/rules.d/60-persistent-storage.rules /etc/udev/rules.d/60-persistent-storage.rules
- Change the following text in the file ‘/etc/udev/rules.d/60-persistent-storage.rules’
- before
# probe filesystem metadata of disks
KERNEL!="sr*", IMPORT{builtin}="blkid"
- after
# probe filesystem metadata of disks
KERNEL!="sr*|snap*", IMPORT{builtin}="blkid"
- Reboot the server.
- Run Backup.
