[lustre-discuss] mdt and mgt are always in RO mode

[Ran Mo]

Greenings,

I tried installed Lustre many time (both 2.15.6 and 2.15.7) but mdt and mgt are always under read only mode.
=====
[root at mds_node ~]# mount | grep nvme
/dev/nvme0n1p1 on /boot type xfs (rw,relatime,attr2,inode64,logbufs=8,logbsize=32k,noquota)
/dev/nvme0n2 on /mnt/mgt type lustre (ro,svname=MGS,nosvc,mgs,osd=osd-ldiskfs,user_xattr,errors=remount-ro)
/dev/nvme0n3 on /mnt/mdt type lustre (ro,svname=lustrefs-MDT0000,mgsnode=192.168.31.20 at tcp0:192.168.31.20 at tcp,osd=osd-ldiskfs,user_xattr,errors=remount-ro,_netdev)
[root at mds_node ~]#

I tried umount and mount and other methods, but unfortunately, cannot get it into RW mode.

Can you give me a hint please? Thanks,

Ran
