Hey all, I have been trying to run a few test with ccd and squid cache. Squid requires a great deal of random access and seek operations as the data is spread all over the squid cache partitions. I was planning on using 3 IBM DDRS-39130W S92A connected in a chain to a 2940UW. I decided to use ccd and see how it compares to just having 3 disks mounted seperatly. Here are the questions: a) ccdconfig -v ccd0 65536 0x02 /dev/sd0c /dev/sd1c /dev/sd2c is the command I use to make the device. I can mount it then at an place on the file system (say mount /dev/ccd0c /mnt) but I can't write, ls, cd or do anything to that partition. Am I missing something here? b) when trying to look at the size of the ccd (with df -k) I see that the system shows the size on one disk, not all three of them (every disk is 9.1GB). From the man page I understood that the 0x02 flag will add the disks together so I was expecting to find a 27GB disk not one 9GB disk. advise, explanation? add to FAQ? 10x Jambi _______________________________________________ Jambi Ganbar | (619) 8220938 | jambi@nlanr.net San Diego SuperComputer Center ________________________________________________ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
