Re: [reiserfs-list] % of filesystem using tails/tail unpacking (shred related)

Re: [reiserfs-list] Tail compression

On Wed, 16 Jan 2002 15:22:45 GMT, toad [EMAIL PROTECTED] said: Hi. Reiserfs packs small files well, and has problems with large tails. So would it make sense to try to gzip tails before packing? AIX already supports this sort of compression. Interestingly enough, they use LZ compression

Re: [reiserfs-list] Tail compression

On Wed, 16 Jan 2002 19:22:58 GMT, toad said: If you're cpu-bound, you probably don't want to compress anything, unless a smaller tail is a lot easier to pack, which the reiserfs docs seem to suggest... possibly this won't gain you enough to offset the cost of compression though. Benchmarking

Re: [reiserfs-list] reiserfs on iSCSI disk

see if you can configure your iSCSI to delay reporting a write as complete until it's actually committed to the platters - that will close most of the race conditions (at the cost of write performance). -- Valdis Kletnieks Operating
