wolverine (128.182.58.80) is configured as a SLASH2 metadata server. Below is a dump of the ZFS configuration:
(pauln@wolverine:zpool)$ sudo ./zpool status pool: wolverine_pool state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM wolverine_pool ONLINE 0 0 0 raidz1 ONLINE 0 0 0 sdb1 ONLINE 0 0 0 sdc1 ONLINE 0 0 0 sdd1 ONLINE 0 0 0 errors: No known data errors
To date I’ve been able to successfully run a 10 million file create test (and unlink). Here’s the fio test config:
group 8peReadWrite { files_per_dir = 1024; tree_depth = 8; tree_width = 3; pes = 4; test_freq = 0; block_freq = 0; path = /slashfs_client/pauln; output_path = /tmp; filename = 8paeRW_1mbs; file_size = 128m; block_size = 4m; thrash_lock = yes; samedir = yes; samefile = no; intersperse = no; seekoff = no; fsync_block = no; verify = yes; barrier = yes; time_block = no; block_barrier = no; time_barrier = no; iterations = 1; debug_conf = no; debug_block = no; debug_memory = no; debug_buffer = no; debug_output = no; debug_dtree = no; debug_barrier = no; debug_iofunc = no; iotests ( WriteEmUp [create:openwr:close] statem [stat] ) }
