Hi GRML. I appreciate your system, have been using since 2008.
Recently learned about persistency which I plan to use to replace custom
initramfs for booting & maintenance of RAID1/LVM2 systems containing
root partitions.
I just finished migrating Gentoo from single partition to mirrored
( RAID1 ) and LVM2 volumes. In the process, I learned/realized that the
Ext3 filesystems contained within raid/volume group are not enabling
write barriers despite being told by fstab to do so. This is 2.6.36
kernel with lvm2 version 2.02.73. I thought to try to grml 2010.12 as
well, but problem remains.
My question: is there any magic "Start" besides mdadm-raid, lvm that
should be necessary ? We can otherwise mount partitions without
incident. Does somebody have ext3 barriers enabled by default such that
I know it should be realized with 2010.12 ?
Appreciatively,
Sven
