RAID-Z is single-fault tolerant. If if you take out two disks, then you no longer have the required redundancy to maintain your data. Build 42 should contain double-parity RAID-Z, which will allow you to sustain two simulataneous disk failures without dataloss.
For an overview of ZFS fault tolerance, you should check out the ZFS administration guide: http://docs.sun.com/app/docs/doc/817-2271 For a description of how RAID-Z works internally, you should look at Jeff's blog: http://blogs.sun.com/roller/page/bonwick?entry=raid_z - Eric On Fri, May 26, 2006 at 10:08:45AM -0700, axa wrote: > Hi here, > > I've a storage with 12 SCSI disks which be configured raidz . > > I tried to take out 2 SCSI disks when data are writing in the raidz > pool.After i token out disks in couple of mins the raidz pool crash !!!!
