The MGS/MDT pool and filesystem were created using these commands:
zpool create -f -o ashift=12 -O canmount=off lustre-mgs-mdt
mirror /dev/disk/by-path/pci-0000:00:1f.2-scsi-0:0:0:0
/dev/disk/by-path/pci-0000:
00:1f.2-scsi-1:0:0:0
mkfs.lustre --mgs --mdt --fsname=iconfs --backfstype=zfs --dev
ice-size 131072 --index=0 lustre-mgs-mdt/mgsmdt0
However, now the MDT is full, and 8 OSTs are 86% full.
lustre-mgs-mdt/mgsmdt0
73G 73G 0 100% /mnt/lustre/local/mgsmdt
lustre-ost0/ost0 13T 11T 1.8T 86% /mnt/lustre/local/ost0
Is there a way to clear space, or will the filesystem/MDT need rebuilt?
Previously, the same disks were used for creating a mirrored MDT w/o
-ashift=12, and did not fill up even when the OSTs were at 89%.
Thanks for any advice.
