Dear list,
Our MDS losts 5/7 osc devices after a reconfiguration:
1.umount all osts
2.tunfs.lustre --writeconf --mgs --mdt /dev/sda1
3.mount -t ldiskfs mdtdevice mountpoint
4.rm CONFIGS/*
5.mount -t lustre mdtdevice mountpoint
6. mount all osts
we can see 7 the osc devices on a mounted client, but only 2/7 osc
devices on MDS. When I create a file with 7 stripe, the MDS server crashed. Any
ideas?
lctl dl

This is a small lustre installation. We have only 2 server, there are 3
OSTs and 1 MDT/MGS on one server, 4 OSTs on the other server. The lustre
version is : 2.6.9-67.0.22.EL_lustre.1.6.6smp on x86-64.
Best Regards
