This evening, I noticed that "dpkg --configure memtest86 +" produced a "grub-mount" process :
# ps axf [...] 21980 pts/2 S+ 0:00 \_ sudo apt-get -f install 21981 pts/2 S+ 0:01 \_ apt-get -f install 21989 pts/4 Ss+ 0:00 \_ /usr/bin/dpkg --status-fd 67 --configure memtest86+:amd64 ubuntu-standard:amd64 21990 pts/4 S+ 0:00 \_ /usr/bin/perl -w /usr/share/debconf/frontend /var/lib/dpkg/info/memtest86+.postinst configure 4.20-1ubuntu1 21997 pts/4 Z+ 0:00 \_ [memtest86+.post] <defunct> [...] 23816 ?

So the problem was not the Reiser4 filesystems, it was the LVM snapshot. # lvdisplay /dev/mapper/vglinux1-lv_ubunutu_oneiric --- Logical volume --- LV Name /dev/vglinux1/lv_ubunutu_oneiric VG Name vglinux1 LV UUID e8GxvT-YwJx-HQXW-ryD9-5zya-tI0g-J7Qosz LV Write Access read/write LV snapshot status active destination for /dev/vglinux1/lv_ubuntu LV Status available # open 0 LV Size 10,00 GiB Current LE 2560 COW-table size 10,00 GiB COW-table LE 2560 Allocated to snapshot 50,56% Snapshot chunk size 512,00 KiB Segments 2 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 252:13 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/970260 Title: Setting up memtest86+ hangs because of "grub-probe: error: unknown filesystem" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/memtest86+/+bug/970260/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
