I am managing a Lustre 2.12.6 system where I have just discovered that the MGS and MDTs are on single disks rather than RAIDed drives.
/dev/sda5 on /mnt/lustre_mgs type lustre (ro,svname=MGS,nosvc,mgs,osd=osd-ldiskfs,...) /dev/sdc1 on /mnt/lustre_mdt_abc type lustre (ro,svname=lstr_abc-MDT0000,mgsnode=10.58.255.254@o2ib,osd=osd-ldiskfs,...) /dev/sdb1 on /mnt/lustre_mdt_def type lustre (ro,svname=lstr_def-MDT0000,mgsnode=10.58.255.254@o2ib,osd=osd-ldiskfs,...) Is there any way to migrate those three metadata partitions to other partitions which would presumably be located on RAIDed drives? For example, would it work to set up the new RAIDed drives and use dd to clone the partitions into partitions on the RAID? .. Lana ([email protected])
