# sysctl -a | grep dirhash
UFS dirhash 895 181K - 550269
16,32,64,128,256,512,1024,2048,4096
vfs.ufs.dirhash_minsize: 2560
vfs.ufs.dirhash_maxmem: 2097152
vfs.ufs.dirhash_mem: 2065716
vfs.ufs.dirhash_docheck: 0
Interesting at all ? Above ^^^ is the output for
today, but I checked it yesterday as well and got:
# sysctl -a | grep dirhash
UFS dirhash 180 43K - 452370
16,32,64,128,256,512,1024,2048,4096
vfs.ufs.dirhash_minsize: 2560
vfs.ufs.dirhash_maxmem: 2097152
vfs.ufs.dirhash_mem: 860405
vfs.ufs.dirhash_docheck: 0
So do I understand this correctly that right now I am
at ~550000 and yesterday I was at ~452000, but
yesterday my high water mark was ~860000 and today my
high water mark is 2065716 ?
So it looks like I maxed it out last night ?
