I think we should not tweak ro_partition because it guarantee foreign OS's partition intact. However we have to know why the partition would require recovery on it. Perhaps it got un-properly shutdown in foreign OS ? We have to make sure everything is sound at first. I am not an expert in file system or block device so can't tell too much, but your workaround seems best to me so far .. I'm not certain who can help on diagnose the other possible cause and solution to this problem. :( -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I try to mount it manually. mount -v -o ro /dev/sda6 /mnt mount: you didn't specify a filesystem type for /dev/sda6 I will try type ext4 /dev/sda6 on /mnt type ext4 (ro) And it works, without complaining I could have specified the file system but os-prober doesn't either (I might have to double check though).

That's one of the problem with this bug: you know that it will happen again some time but it is hard to reproduce.

I did not ask to reproduce. I asked for logs of something that already happened. /var/log/messages is normally stored persistently and is kept for at least some time ... in my case history goes as far as one year. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Sorry : grub2 does not detect all OS of a machine. My English is poor and I don't know how to say to you what I think. There is a correlation.

Both bugs have the consequence that the boot entries for foreign operating systems are missing, but there is no other correlation. The Linux bug discussed here is related to the ext2 file system and journaling at a pretty low level, I think. IMO, only a ext2 expert will be able to sort it (without using hacks). The BSD bug is either ignoring ufs partitions or failing to mount them properly, due to a syntax error (wrong mount option: 44bsd vs ufs2) in os-prober scripts. This bug will be easy to fix, as soon as maintainers are interested in fixing it (I fixed it a long time ago). Further you'll have to add a script in Grub2 to write NetBSD or other BSD entries, but this is not difficult. Whether they will effectively boot BSD kernels is another problem. In the past (with legacy Grub), it used to work or not. In any case, chainloading - as you already mentioned - is always possible, but it's a work around to a specific problem in a given situation, and not a bugfix. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
