Re: [9fans] Fossil+Venti system memory requirements to be aware of?

Hi Jim, It's important to point out that the arena size does not have to match the size of an arenas file. In my case, I do something similar where I use 2GB for an arena but keep my arenas files at 2GB (I don't have much use for keeping multiple arena files). More indexes help to an extent. My f

i agree absolutely with steve here, expanding venture arena by arena is easy, the ventibackup scripts show you how. even easier is to add arenas on a different disk partition to the same venti. personally i wouldn't keep music or videos in venti. they don't compress well using the arithmetic te

Hi Jim, It probably helps to break apart fossil and venti for the sake of the conversation. While you can use fossil as a standalone filesystem, it is effectively your write cache in this scenario since it will be backed by venti. Conventional wisdom is to size your main fossil fs based on how muc

Anyone able to tell me whether or not there are disk size limits I should beware of given a limited amount of system memory in a file server? What I'm wanting to try and do is get a hardware RAID1+0 enclosure and put in 20TB of disk (so 10TB of usable space). The board I am looking at will take
