I just upgraded from 3.4-STABLE to 4.0-STABLE and am having problems mounting my Linux partition. The Linux root filesystem is on /dev/da0s3. Here's what happens: # mount -t ext2fs /dev/da0s3 /mnt/linux ext2fs: /dev/da0s3: Invalid argument # ls -l /dev/da0s3 crw-r----- 1 root operator 13, 0x00040002 Mar 28 11:35 /dev/da0s3 Syslog reports: /kernel: WARNING: R/W mount of #da/0x40002 denied due to unsupported optional features Huh? To what "unsupported optional features" is it referring? In case it matters, the Linux installation is Red Hat 6.1. And I do have options EXT2FS in my kernel config. I thought maybe the filesystem wasn't clean, so I booted Linux and fsck'ed, only to get the same results. Thanks for any help, or pointers to documentation that I should have read... -Eric FreeBSD 4.0-STABLE #0: Thu Mar 23 15:16:02 EST 2000 To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-stable" in the body of the message
