Red Hat Bugzilla – Bug 1299879
check_vol_slaves() in dracut-functions.sh does not strip whitespaces from volume group name
Last modified: 2016-11-04 04:02:51 EDT
Description of problem:
When I run dracut --debug I get following:
//usr/lib/dracut/dracut-functions.sh@688(check_vol_slaves): lvm lvs --noheadings -o vg_name /dev/mapper/os-root
/usr/lib/dracut/dracut-functions.sh@688(check_vol_slaves): _vg=' os '
//usr/lib/dracut/dracut-functions.sh@690(check_vol_slaves): printf '%s\n' ' os '
/usr/lib/dracut/dracut-functions.sh@690(check_vol_slaves): _vg=' os '
/usr/lib/dracut/dracut-functions.sh@691(check_vol_slaves): [[ -n os ]]
//usr/lib/dracut/dracut-functions.sh@684(check_vol_slaves): lvm vgs --noheadings -o pv_name ' os '
/usr/lib/dracut/dracut-functions.sh@699(check_vol_slaves): return 1
So there're whitespaces that cause check_vol_slaves() to fail.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Have LVM with a volume group named as "os" and have the root LV on that vg
2. run `dracut /tmp/dracut-test.img --debug`
Dracut fails to query the volume group because of escaped whitespaces
Whitespaces should be striped off before attempting to run vgs
