Re: [zfs-discuss] How's zfs RAIDZ fualt-tolerant ???
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. I'm not sure if this has been mentioned elsewhere (I didn't see it..) but will this double parity be backported into Solaris 10 in time for making the U2 release? This is a sorely needed piece of functionality for my deployment (and I'm sure many others.)
