I just used Debian Testing to recover data from a set of failing SSDs.
With the added difficulty, the new one had to go back in its CentOS 6 host.
It turns out that ext4 defaults had been updated since the release of CentOS 6, and the kernel doesn't support ext4 with 64bit and R10(still not sure what this is).
tar xzf v1.45.*.tar.gz
./misc/tune2fs -O ^64bit /dev/mapper/vg-lv
./e2fsck/e2fsck -f /dev/mapper/vg-lv
./misc/resize -s /dev/mapper/vg-lv
./misc/tune2fs -O ^has_journal,^FEATURE_R10 /dev/mapper/vg-lv
tune2fs -j /dev/mapper/vg-lv
fsck.ext4 -f /dev/mapper/vg-lv
Linux fueled mayhem & madness with a side of news, reviews, and whatever the Hell-Elks™ we come up with.
