It consists of 3 66M HP SCSI drives concatenated inot 1 1.8G filesyste, Createing the ccd and mounting it goise OK. Then I start a tar operation to move about 1.2M worth of data to this ccd. The machine is runing the normal load for eerything els. Somewhere *after* 33% (one complete disks worth?) of data is written to these drives the machine reboots itslef. This has happende 4 times at this point. The last time it just hung istead of rebooting. OnceI caught the error message it was: tar: couldn't write to file debian/bo/source/misc/bl_1.2-2.dsc : File too large This file is very small!Once the machine is rebooted, an arempt to fsck the ccd fails with some very strange errors such as negative inode numbers, and truncated inodes. I believe thateither there must be a bug in the ccd driver, or perhaps I have somehow set it up incorectly. Here is what i did to set it up: recompile kernel with ccd osuedo-driver do MAKDEV ccd0 diskalabel -r -w auto each of the drives. diskalabel -e ecah of the drives and chane the partiton type for the c partition to 4.2BSD ccdconfig ccd0 16 o /dev/sd0c /fev/sd1c /dev/sd2c newfs /dev/rccd0 mount the /dev/ccd0c /mirror and then I. tar cf -. | ( cd /mirror ; tar xvf -) and about 30 minutes laer the system crashes, reliably. Ths machine has been rock solid for over a year now. It is my main communications server, and I have reached the point where I am tired of crashing it. Can someone give me some advice here? Have I done somthing wrong? Is this a nown bug? I'm on 2.2 STABLE from a few months agoa. cvsupedwith the 2-2RELENG tag.
