Description Paul Monsour 2009-11-11 03:06:05 UTC

After upgrading to portage-2.2_rc49, I cannot emerge most ebuilds. Typical output is this (from net-libs/xulrunner-1.9.1.5):

Reproducible: Always

Steps to Reproduce:
1. Emerge almost any package (e.g., xulrunner, glibc, openssl)
2. 
3.

Actual Results:  
Here is the result of trying to emerge glibc:

Expected Results:  
Successful emerge.

Some packages did emerge after installing the new portage, such as app-admin/eselect-opengl-1.1.1 and media-gfx/grub-splashes-20091109 and sys-fs/mdadm-3.0.3.

Comment 1 Paul Monsour 2009-11-14 15:32:43 UTC

(In reply to comment #0)

Tried checking the filesystem, and /var/tmp, /var, and /usr (separate lvm's on a raid5 array) were all faulty. Ran fsck.reiserfs --rebuild-tree and can now emerge again. There are lingering problems, but I'm assuming they are related to the corrupted files.
