df(1) vnconfig(8) hanging ....
Hi all, This morning I wanted to edit an ISO to instruct the kernel to redirect its output to serial. i.e # sudo vnconfig -v -c /dev/vn0 5.3-BETA1-i386-miniinst.iso # sudo mount -t cd9660 -o rw /dev/vn0 /mnt # sudo tcsh # echo /boot/loader -h boot.config boot.config: Read-only file system. Forget the afforementioned error. The problem that I have is now when I issue a df(1) my shell hangs: e.g. # df -h ^C^C^D ^C^C^D # ps -aux | grep df username 0.0 0.0 212 96 p2 D+9:04AM 0:00.00 df -h username 3332 0.0 0.0 212 96 p1 D+9:04AM 0:00.00 df -h # kill -9 3332 # ps -aux | grep df username 0.0 0.0 212 96 p2 D+9:04AM 0:00.00 df -h username 3332 0.0 0.0 212 96 p1 D+9:04AM 0:00.00 df -h No change. I'm not sure what has hung here, nor am I sure how to 'un-hang' my shell. Any thoughts anyone ? - aW ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I think it depends how you mount it as to how long the kernel will wait before unmounting it. - -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au The nice thing about standards is that there are so many of them to choose from. -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C -BEGIN PGP SIGNATURE- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFBKo7Q5ZPcIHs/zowRAmkAAKCKk/7ycWS2+sWc7tBYc4T03AbOLQCfaaxc 2sZ8/pYP2sumd8C+RONwdTs= =P2r0 -END PGP SIGNATURE- ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
