Seems for my application (RAID0), *gstripe* is what I should be using. Q: But RAID0 provides 0 redundancy. How will you cope with data loss? A: Complete backups occur twice daily and I (we) use IP RAID0 - eg; 2 different servers have/provide the same data, and the DNS provides "round-robin". Thereby spreading the requests roughly equal across both servers. So, given my new found knowledge. I felt I should probably ask before potentially clobbering (breaking) the server I'll be attempting this on. Will the following accomplish my goal? Current setup: /dev indicates the following: da0, da0c, da0cs1, da0s1, da0s1c da1, da1c, da1cs1, da1s1, da1s1c da2, da2c, da2cs1, da2s1, da2s1c ...and the following, which FreeBSD is installed on: da3, da3s1, da3s1a, da3s1b, da3s1c, da3s1d All drives are of same size/make/model. Given the above, I intend to issue the following: # gstripe label -v -s 131072 bigstripe \ /dev/da0 /dev/da1 /dev/da2 /dev/da3 # newfs -U /dev/stripe/bigstripe # mount /dev/stripe/bigstripe /bigstripe # echo 'geom_stripe_load="YES"' >> /boot/loader.conf # echo '/dev/stripe/bigstripe /bigstripe ufs rw 2 2' >> /etc/fstab Or do/should I issue: # gconcat label -v extradisks /dev/da0 /dev/da1 /dev/da2 # gstripe label -v bigstripe /dev/da3 /dev/concat/extradisks # bsdlabel -wB /dev/stripe/bigstripe # newfs -U /dev/stripe/bigstripe # mount /dev/stripe/bigstripe /bigstripe Thank you for all your time and consideration. Chris P.S. I know this is a bit noisy. I intend to keep it brief.
