Hi. If I create a zpool with the following command:
zpool create tank raidz2 da0 da1 da2 da3 da4 da5 da6 da7 and after a reboot the device names for some reason are changed so da2 and da5 are swapped, either by altering the LUN setting on the storage or by switching cables/swapping disks etc.? How will zfs handle that? Will it simply acknowledge that all devices are present and the pool is intact and report online or will it complain? The reason I ask is that six months ago I had two seperate storage systems on veritas volume manager (vxfs) attached to my solaris-9-nfs-server via a fiber-switch. I migrated all volumes from the smaller storage-system to the larger one and disconnected it. All went fine and the system was humming along. The fiber-switch rebooted three weeks ago and some of the devices (LUN's) went into state failing as seen by veritas so I had to online the devices and fsck the volumes that went offline. The tape-drive also took a hit and so I did a devfsadm to have the devices (re)created. But then a device changed name from c3t1d0s2 to c3t0d0s2 and now veritas report the disk as missing and one volume as unavailable. regards Claus _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
