How to check savvol space used by replication
I've read "How to check the actual space usage by checkpoint" and that works for a source FS with a checkpoint and replication enabled.
nas_fs -size
However, I'm looking at my replication target FS that does not have any checkpoints and cannot use the same command to find the exact space used in MB (I have DART 5.6).
One workaround that I can think of is to create a checkpoint on the replication target FS and then run nas_fs command. But that's two additional steps (creating and deleting) per FS.
Is there another way to get the same results.
Thanks,

there should be two replication checkpoints per file system on target celerra, you can see them by running server_mount
and then you can look at their size
/nas/sbin/rootnas_fs -size root_rep_ckpt_513_60358_2

Hi,
what dynamox stated is completely correct, but here is another way to check it :
# nas_fs -query:type==ckpt -fields:BackupOf,name,size -format:"%s %s %sMB\n"
ttt ttt_ckpt3 100MB
dedupe root_rep_ckpt_616_74061_1 20000MB
dedupe root_rep_ckpt_616_74061_2 20000MB
dedupe_replica1 root_rep_ckpt_623_74069_1 20000MB
dedupe_replica1 root_rep_ckpt_623_74069_2 20000MB
ttt ttt_ckpt1 100MB
ttt ttt_ckpt2 100MB
dedupe root_rep_ckpt_616_228523_2 20000MB
nmfs1 root_rep_ckpt_802_438077_1 1024MB
nmfs1 root_rep_ckpt_802_438077_2 1024MB
dedupe dedupe_ckpt1 20000MB
dedupe root_rep_ckpt_616_228523_1 20000MB
filesystem filesystem_ckpt1 10240MB
gustavo gustavo_ckpt1 20000MB
The first column is the PFS ( Production file system ), the second one the checkpoint ( no matter if it's a normal or an internal rep ckpt ), and the third, the SavVol size.
