[zfs-discuss] Cause for data corruption?

hi folks I've been running my fileserver at home with linux for a couple of years and last week I finally reinstalled it with solaris 10 u4. I borrowed a bunch of disks from a friend, copied over all the files, reinstalled my fileserver and copied the data back. Everything went fine, but

[zfs-discuss] Panic when ZFS pool goes down?

2008-02-25 Thread Vincent Fox
Is it still the case that there is a kernel panic if the device(s) with the ZFS pool die? I was thinking to attach some cheap SATA disks to a system to use for nearline storage. Then I could use ZFS send/recv on the local system (without ssh) to keep backups of the stuff in the main pool.

Hello all, I just did this post about the problem: http://www.posix.brte.com.br/blog/?p=103 I just want to know if somebody knows the Linux implementation of XFS, EXT3, or another filesystem to confirm that the ACK by the fileserver is without log the transaction (like ZIL), or without commit

2008-02-25 Thread Nathan Kroenert
My guess is that you have some defective hardware in the system that's causing bit flips in the checksum or the data payload. I'd suggest running some sort of system diagnostics for a few hours to see if you can locate the bad piece of hardware. My suspicion would be your memory or CPU, but

For Linux NFS service, it's a option in /etc/exports. The default for modern (post-1.0.1) NFS utilities is sync, which means that data and metadata will be written to the disk whenever NFS requires it (generally upon an NFS COMMIT operation). This is the same as Solaris with UFS, or with

How do you use CDP backups? How do you decide at which write(2) (or dirty page write, or fsync(2), ...) to restore some file? What if the app has many files? Point-in-time? Sure, but since you can't restore all application state (unless you're checkpointing processes too) then how can you be
