Description
Lola's Lustre file system "home" was formatted with a recent master build. I downgraded it to b2_5 (lustre-b2_5 96) and immediately hit this MDT mount failure:
192.168.1.108: mount.lustre: mount /dev/mapper/360080e50002ffd8200000251520130a4 at /mnt/home-mdt1 failed: Numerical result out of range
This is the ldiskfs-based home-MDT0001. (On the other hand, home-MDT0000 is ZFS-based and was successfully mounted at the beginning.) From 192.168.1.108's dmesg:
