Hello everybody.
I've got 2 FAS 2220 with 8.1.1 7-mode.
I activated asynchronous snapmirroring (on nfs_logs) , and it's working fine, but I can see that agregate free space is going down.
The first time (before snapmirroring), the output was like it:
aggr show_space -h
Aggregate 'aggr0'
Total space WAFL reserve Snap reserve Usable space BSR NVLOG A-SIS Smtape
24TB 2479GB 0KB 21TB 0KB 0KB 0KB
Space allocated to volumes in the aggregate
Volume Allocated Used Guarantee
vol0 173GB 4258MB volume
nfs_logs 21TB 105MB volume
Aggregate Allocated Used Avail
Total space 21TB 4363MB 626GB
Snap reserve 0KB 0KB 0KB
WAFL reserve 2479GB 18GB 2460GB
Now :
aggr show_space -h
Aggregate 'aggr0'
Total space WAFL reserve Snap reserve Usable space BSR NVLOG A-SIS Smtape
24TB 2479GB 0KB 21TB 0KB 0KB 0KB
Space allocated to volumes in the aggregate
Volume Allocated Used Guarantee
vol0 173GB 4653MB volume
nfs_logs 21TB 8425MB volume
Aggregate Allocated Used Avail
Total space 21TB 12GB 614GB
Snap reserve 0KB 11GB 0KB
WAFL reserve 2479GB 18GB 2460GB
I dont't understand why snap reserve is growing, because agregate scheduling isn't working:
snap sched -A
Aggregate aggr0: 0 0 0
Thanks
