Re: [zfs-discuss] Multiple Read one Writer Filesystem

2007-01-14 Thread Erik Trimble
Not to be a ninny, but a one-write/many read is pretty much the design scenario for using CacheFS in conjunction with NFS on the client side. That is, assuming that only one client is doing the writing. If all your clients are doing writing (just maybe not to the same file), then you DON'T hav

Thanks for the feedback, it seems caching is the main concern and if I always only write any given file once (then perhaps do a flush and a close after the write to empty the cache) and from then only ever read the file, will the scheme I had in mind work? Also, will ZFS really prevent my moun

Hi, I am considering using ZFS so that multiple clients can "share" the same filesystem. I know that ZFS does not support a distributed filesystem. The alternative I am considering is to have a single filesystem available to many clients using a SAN (iSCSI in this case). However only one clien
