From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030922 Description of problem: I came across this during RH300 training. While initialising 4 partions using pvcreate I tried to cut corners by instead of doing : pvcreate /dev/hda9 pvcreate /dev/hda10 pvcreate /dev/hda11 pvcreate /dev/hda12 I attempted this instead: pvcreate /dev/hda[9-12] This then destroyed /dev/hda2 - without any warning (and it was mounted on /usr !) After rebuilding the system I repeated the issue using variations of this command line. Results below: pvcreate /dev/hda[9-10] [root@station1 RPMS]# pvcreate /dev/hda[9-10] pvcreate -- invalid physical volume name "/dev/hda[9-10]" pvcreate /dev/hda[9-11] destroyed /dev/hda1 pvcreate /dev/hda[9-12] destroyed /dev/hda2 Version-Release number of selected component (if applicable): lvm-1.0.3-15 How reproducible: Always Steps to Reproduce: shown in description Actual Results: shown in description Expected Results: shown in description Additional info: shown in description
Always use 'echo' to check how the shell will expand what you type: echo pvcreate /dev/hda[9-11] gives pvcreate /dev/hda1 To understand this, read the man page for your shell eg the 'Pattern Matching' section of 'man bash'.
