Hello, I've did an e2fsck on my MDT and after that I could not mount the MDT anymore It gives me this error when I've tried to mount the filesystem any ideas how to resolve this?
We are running Lustre server 2.12.7 on CentOS 7.9 mount.lustre: mount /dev/mapper/****-MDT0000 at /lustre/****-MDT0000 failed: File exists Mar 2 10:58:35 mds01 kernel: LDISKFS-fs (dm-19): mounted filesystem with ordered mode.
