We have a 32 GB RAM server running about 14 zones. There are multiple databases, application servers, web servers, and ftp servers running in the various zones. I understand that using ZFS will increase kernel memory usage, however I am a bit concerned at this point. root at servername:~/zonecfg #mdb -k Loading modules: [ unix krtld genunix specfs dtrace uppc pcplusmp ufs md mpt ip indmux ptm

Would someone "in the know" be willing to write up (preferably blog) definitive definitions/explanations of all the arcstats provided via kstat? I''m struggling with proper interpretation of certain values, namely "p", "memory_throttle_count", and the mru/mfu+ghost hit vs demand/prefetch hit counters. I think I''ve got it figured out, but

Greetings, all. Does anyone have a good whitepaper or three on how ZFS uses memory and swap? I did some Googling, but found nothing that was useful. The reason I ask is that we have a small issue with some of our DBA''s. We have a server with 16GB of memory, and they are looking at moving over databases to it from a smaller system. The catch is that they are moving to 10g. Oracle

Ok, so I ran fsck manually (even with -y), but yet it refuses to clear/fix whatever to the questions posed as fsck runs. What does this all mean?
