Hi!
I have a RedHat 7.2 machine installed from scratch. Recently I installed RedHat 7.2 on another machine that has two harddisks (/dev/hda and /dev/hdc) The second is in a removable bay. Linux was installed on /dev/hdc.
My main machine also has a hdd bay (/dev/hdc) and I have put the new machine's removable hdd into the main one and booted up. (I had to copy some files and no network between the machines.)
On boot I had strange errors that said that this and that partitions cannot be found. I observed the following.
The / partition contains the main machine's data from /dev/hda2 although the mount command lists / as mounted from /dev/hdcX. Every other partitions are mounted from /dev/hdc.
The problem is that /etc/fstab as used by RedHat, lists the partition by LABEL=/mountpoint which labels can be found on both /dev/hda and /dev/hdc.
The /proc/partitions "file" lists the partitions in disk-reversed order, e.g.:
/dev/hdc1 .... ... /dev/hdc10 ... /dev/hda1 ... ... /dev/hda9 ...
Is there a way to fix this? Yes there is: vendors should not use LABEL=XXX method in /etc/fstab. Either use the proper device/partition or the UUID. The downside is that fsck messages would not be as pretty-printed as now. Or maybe the partitions should not be registered in disk-reversed order...
Best regards, Zoltán Böszörményi
