For me, Red Hat 6.1 and kernel 2.2.12, but you'll get the same answer with Slackware 7. The key attributes are: Filesystem revision #: 1 (dynamic) Filesystem features: sparse_super You'll need a filesystem without sparse_super and probably revision 0. > Is there a way, perhaps in Linux with its tunefs, to adjust or > "turn off" those "optional features" (other things too?) in such > a way that FreeBSD's ext2 support will work? As a workaround, you can boot a Linux live filesystem or rescue disk and manually run mke2fs as: # mke2fs -r0 -s0 /dev/whatever Then reinstall Linux, telling it to NOT reformat the partitions. Of course, this will erase any data on the partition, so you'll have to either dump or tar the filesystem or else reinstall from scratch. I don't think you can turn off these features without remaking the partition. But I think the real answer to Kenneth's and my question is that Freebsd doesn't support these optional features and isn't likely to in the near future. Can anyone offer a more optimistic outlook? --Mark Krentel To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
