Description Olivier Kurzweg 2007-04-01 22:23:12 UTC
Description of problem:
From time to time, my sil RAID1 array gets out of sync and I need to rebuild the
array. When this happens, an new name gets generated for it: name sil_xxxxxxxxx
changes to sil_yyyyyyyyyy. Since the init script still has reference to the old
name, block devices get created with the old name at boot time.

'dmsetup table' returns "sil_xxxxxxxxxx". But dmraid returns "sil_yyyyyyyyyyyy".

In that situation, mkinitrd will fail to add the necessary 'dm create' lines in
the init script: it looks up for entries from the "dmestup table" that match
entries from the "dmraid -s" output and finds none.

Workaround: run a 'dmsetup rename sil_xxxxxxxxxx sil_yyyyyyyyyyyy' before
running mkinitrd.

Version-Release number of selected component (if applicable):

Steps to Reproduce:
1. Break and rebuild raid array (new name gets generated)
2. Run mkinitrd
Actual results:
mkinitrd does not "see" the new array and do not add the 'dm create' lines in
the init script  

Expected results:
mkinitrd should not rely on the name returned by dmsetup table, or should not
try to find a match in the output of dmraid -s
