hammer mirror shows differrent results from differrent terminals

[Siju George <sgeorge.ml@xxxxxxxxx>]

Hi,

I have a master pfs and slave pfs in two differrent disks.

#hammer pfs-status /Backup1/Data
/Backup1/Data   PFS #1 {
    sync-beg-tid=0x0000000000000001
    sync-end-tid=0x00000001000204b0
    shared-uuid=94063778-6ac7-11de-a994-011617202aa6
    unique-uuid=940637b5-6ac7-11de-a994-011617202aa6
    label=""
    operating as a MASTER
    snapshots dir for master defaults to <fs>/snapshots
}

 #hammer pfs-status /Backup2/Data
/Backup2/Data   PFS #1 {
    sync-beg-tid=0x0000000000000001
    sync-end-tid=0x00000001000204b0
    shared-uuid=94063778-6ac7-11de-a994-011617202aa6
    unique-uuid=b015e877-6ac7-11de-a994-011617202aa6
    slave
    label=""
    operating as a SLAVE
    snapshots directory not set for slave
}

master in null mounted and slave has a soft link to the real pfs

/Backup1/pfs/@@-1:00001 on /Backup1/Data (null, local)

dfly-bkpsrv# ls -l /Backup2/Data
lrwxr-xr-x  1 root  wheel  17 Jul  7 13:18 /Backup2/Data -> /Backup2/pfs/Data



Now I ssh into the system through an xterm (xterm1) and move to the master.

# pwd
/Backup1/Data

Now I ssh into the system through another xterm (xterm2) and move to slave

# pwd
/
# cd /Backup2/Data
# pwd
/Backup2/pfs/@@0x00000001000204b0:00001
#

Now in xterm1 I create a test file in the master pfs

# touch test
# ls -l
total 0
-rw-r--r--  1 root  wheel  0 Jul  7 13:44 test
#

Then I do a hammer mirror copy ( in xterm1 ) to slave

# hammer mirror-copy /Backup1/Data /Backup2/Data
Mirror-read: Mirror from 00000001000204b1 to 00000001000204f0
Mirror-read /Backup1/Data succeeded
#

Now I check the slave in xterm2

# pwd
/Backup2/pfs/@@0x00000001000204b0:00001
# ls
#
it shows nothing.
but if I check it with the full path ( in xterm2 ) it shows the file
is mirrored.
# ls -l /Backup2/Data/
total 0
-rw-r--r--  1 root  wheel  0 Jul  7 13:44 test


Why is this so?

now I delete the "test" file and mirror-copy again.

# rm test
# hammer mirror-copy /Backup1/Data /Backup2/Data
Mirror-read: Mirror from 0000000100020371 to 0000000100020370
Mirror-read: No work to do
Mirror-read /Backup1/Data succeeded

It says no work to do!
and the file is left in the slave.

Unfortunately the "no work to do" part could not be reproduced by me.
But the first part is reproducible.

thanks
