In fact, I use a Mylex card and the partition causing the problem is 85GB. What's interesting is that it's supposedly fixed in 2.4. > I'm not sure if this explains why mke2fs works in the > %post environment, and not during the ramdisk > environment.

I looked at the environment variables set during %post, MKE2FS_SYNC is not set. > Martin, or anyone else who is seeing this problem, > what does the alt-f3 and alt-f4 screens show when mke2fs hangs? Hmm, from what I remember, they don't really show anything unusual. Alt-F5 shows the output of mke2fs, and the last line typically says: Writing inode tables: 1/685 > Also, are you using the 2.4.2-ac2 kernel which comes on the > distribution, right? Yes, the kernel that comes with RH 7.1.
