On a system with more than 26 disks, after /dev/sda through /dev/sdz are used, disks start to get names like /dev/sdaa, /dev/sdab, etc. Unfortunately grub-installer doesn't cope with these names; the pattern used to figure out how to compute disc_offered_devfs doesn't match properly and so trying to install a system with the root FS on eg /dev/sdaa fails when trying to install grub.
Fix this by extending the pattern used to match /dev/sdX and /dev/vdX to handle the cases where X is two or three letters (I checked the kernel source, and the sd and vd cases will only use up to three letters; the IDE hd case only uses one letter). cf https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/776633 (I've only tested this with Ubuntu but the upstream grub-installer tree pretty clearly has the same bug) --- grub-installer | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/grub-installer b/grub-installer index 95b6532..c8c1e74 100755 --- a/grub-installer +++ b/grub-installer @@ -231,7 +231,7 @@ case $prefix in /dev/mapper) disc_offered_devfs="$bootfs" ;; - /dev/[hsv]d[a-z0-9]|/dev/xvd[a-z]|/dev/cciss/c[0-9]d[0-9]*|/dev/ida/c[0-9]d[0-9]*|/dev/rs/c[0-9]d[0-9]*|/dev/mmcblk[0-9]|/dev/ad[0-9]*|/dev/da[0-9]*) + /dev/[hsv]d[a-z]|/dev/[sv]d[a-z][a-z]|/dev/[sv]d[a-z][a-z][a-z]|/dev/xvd[a-z]|/dev/cciss/c[0-9]d[0-9]*|/dev/ida/c[0-9]d[0-9]*|/dev/rs/c[0-9]d[0-9]*|/dev/mmcblk[0-9]|/dev/ad[0-9]*|/dev/da[0-9]*) disc_offered_devfs="$prefix" ;; *) -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
