I was just trying to create a large empty file on my DOS partition so that I could play with the vn device. I tried using dd: dd if=/dev/zero of=/dos/d/bsdpart bs=20k count=5000 The disk started chugging and the file started growing and all seemed fine. However, when the file reached about 50M, everything stopped. I couldn't kill the dd process but I could login to another vty and the system seemed basically fine. In the ps list, it claimed that dd was sleeping in getblk. I shutdown and rebooted and when reboot tried to sync the disks, there was one block which refused to be written for about 20 tried until it gave up and rebooted anyway. Is this something obvious to do with the new VM system or is MSDOSFS just plain broken? -- Doug Rabson, RenderMorphics Ltd. Mail: dfr@render.com Phone: +44 71 251 4411 FAX: +44 71 251 0939
