Hello Leal, I've been already warned (http://www.opensolaris.org/jive/message.jspa?messageID=231349) that ZIL could be a cause and I made tests with zil_disabled. I run scrub and system crashed exactly at after the same period and the same error. ZIL known to cause some problems on writes, while all my problems are with zio_read and checksum_verify.
This is NFS file server, but it crashed even when NFS unshared and nfs/server is disabled. So this is not NFS problem. I reduced panic occasions by setting zfs_prefetch_disable. This allows me to avoid unnecessary reads and reduces chances of reading bad checksums. For now I've 24 hours without crash which is much better than few times a day. However, I know that bad checksums are there and I need to fix them somehow. -- Rustam This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
