It doesn't need fsck for the normal case of filesystem corruption due to system crashes: in that case, you stand to lose maybe the last one or two IO transactions that hadn't made it onto the disk yet, but the data that was already on the disk will still be consistent. Needing fsck because the drive is failing and not able to store and retrieve data reliably any more is a whole different thing. ZFS at least will discover that this is happening due to the built-in checksumming and avoid many instances of silent corruption. What it can't do is take a filesystem containing random errors and reconstruct a pristine version from it. But then what filesystem can?

Re: compare zfs xfs and jfs o
i have 16tb storage. 8x2tb sata raided. i want to share it on network via nfs. which file system is better for it? thank you badly imprecise question. you may share any filesystem. Not sure what you want to achieve. No explanation of raided - this means nothing without precise description. If you ask what i do commonly then i would do 8 gmirror-based RAID1 volumes, and standard UFS filesystem on each with softupdates (or softupdates+journal). And move as much as possible software directly to machine. Never create another level of indirection (like NFS) when not needed. if you really HAVE to use NFS heavily i strongly recommend using unfsd from ports and patch if to AVOID constant fsync, and make sure UPS is installed. NFS protocol is terrible by design (not by implementation) resulting in all writes being done synchronously. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
