Quoting "Chris H." <[EMAIL PROTECTED]>:
Hello, I seem to remember a similar question being asked in the past. But never
---8<---snip---8<---
I had originally intended to create a raid mirror on the whole lot of HD's during the install process. But I wasn't presented, nor could I find that option during install. So, due to lack of time, pushed it off till later, and simply installed onto the one HD. Now to my question(s)... Where is the option to create, and install to a gMIRRORED drive-set?

2) In my cases above, I'm interested in RAID-0 (mirroring for /volume/ not redundancy).
OK, my mistake... 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. Thank you for your understanding. :)
