Thanks for looking into this. We do use io-threads. Here is the server
config:
: volume brick1-posix
2: type storage/posix
3: option directory /mnt/brick1
4: end-volume
5:
6: volume brick2-posix
7: type storage/posix
8: option directory /mnt/brick2
9: end-volume
10:
11:
12: volume brick1-locks
13: type features/locks
14: subvolumes brick1-posix
15: end-volume
16:
17: volume brick2-locks
18: type features/locks
19: subvolumes brick2-posix
20: end-volume
21:
22: volume brick1
23: type performance/io-threads
24: option min-threads 16
25: option autoscaling on
26: subvolumes brick1-locks
27: end-volume
28:
29: volume brick2
30: type performance/io-threads
31: option min-threads 16
32: option autoscaling on
33: subvolumes brick2-locks
34: end-volume
35:
36: volume server
37: type protocol/server
38: option transport-type tcp
40: option auth.addr.brick1.allow *
41: option auth.addr.brick2.allow *
42: subvolumes brick1 brick2
43: end-volume
