Recently I found that new kernels were not booting for me, because they could not assemble the LVM partition that I use for the root filesystem.
Booting back to my old kernel still worked. I have tracked this back to the lvm2 version. After booting with the old kernel, I ran lvm and tried the 'fullreport' command. sys-fs/lvm2-2.02.184-r3 gives an error: lvm> fullreport LV root invalid: visible raid meta LV for raid1 segment LV root invalid: visible raid meta LV for raid1 segment Internal error: LV segments corrupted in root. After backing out to an earlier version, sys-fs/lvm2-2.02.183 the 'fullreport' actually gives a report. I'm assuming the only reason the old kernel boots is that it has the older lvm in the initramfs, and once assembled the handover to the live system still works. I can't find anything online that looks like the same thing to me, so I was wondering if anyone here had encountered a similar problem? The next step is to try and find how to update the on-disk lvm meta data so the later versions understand it, hopefully without having to rebuild my system from scratch. -- Reverend Paul Colquhoun, ULC. http://andor.dropbear.id.au/ Asking for technical help in newsgroups?
