i have a snapmirror relationship that was not working. We determined we changed the source vol size but not the destination size (duh). so i did the following:
Step 1 — Temporarily break the mirror to make the volume read/writeable
site2>snapmirror break demo4
Step 2 — Change the volume option of our “demo4″ volume fs_size_fixed to off
site2> vol options demo4 fs_size_fixed off
Step 3 — Increase the size of the destination volume
site2> vol size demo4 +1100g
Step 4 — Change the fs_size_fixed back to on before we resume the mirror
site2> vol options demo4 fs_size_fixed on
Step 5 — Re-establish the mirror
site2>snapmirror resync -S sourcefiler:sourcevolume destinationfiler:destinationvolume
Now the snapmirror has resumed the transfer which is good, but i see on the putty session of the destination when i do a df -h the total size is still set to 3061gb which was the old amount before i added space. i know the fs_size_fixed syncs that information between source & destination so they are identical. my source vol size is: 4085GB.
When does the destination sync up the total size to match the source? Is it after it completes the resync transfer or should it be instantaneous? The space was showing correctly on the destination before i issued the vol options demo4 fs_size_fixed on command.
thanks
