| Fixed In Version: | libguestfs-1.20.9-5.el6 | Doc Type: | Bug Fix | |
| Doc Text: |
Cause: Creating a hard link when using guestmount.
Consequence: If creating the hard link fails, the wrong error was returned. This could result in applications failing, or failing to print the correct error message (making diagnosis of the true causes of problems difficult).
Fix: Error handling in guestmount has been rewritten.
Result: Correct errors are returned to guestmount users.

Description

This request was not resolved in time for the current release. Red Hat invites you to ask your support representative to propose this request, if still desired, for consideration in the next release of Red Hat Enterprise Linux. Unfortunately this missed RHEL 6.4. However it's a fairly serious bug as it turns out. The full description, along with patches, is here: https://bugzilla.redhat.com/show_bug.cgi?id=895905#c4 Fix included in upstream libguestfs 1.16.35. This is fixed by the rebase (bug 958183). Reproduced with libguestfs-1.16.34-1.el6.x86_64 # mkdir mountpoint # guestmount --rw -o allow_root --pid-file guestmount.pid -a RHEL-Server-6.0-32-hvm.raw -m /dev/vg_dhcp669266/lv_root -m /dev/sda1:/boot mountpoint # cd mountpoint/ # touch foo # ln foo boot/foo ln: creating hard link `boot/foo' => `foo': No such file or directory Give error "No such file or directory" Verified with libguestfs-1.20.11-2.el6.x86_64 [root@dhcp-9-42]# guestmount --rw -o allow_root --pid-file guestmount.pid -a RHEL-Server-6.0-32-hvm.raw -m /dev/vg_dhcp669266/lv_root -m /dev/sda1:/boot mountpoint [root@dhcp-9-42]# cd mountpoint/ [root@dhcp-9-42 mountpoint]# touch foo [root@dhcp-9-42 mountpoint]# ln foo boot/foo ln: creating hard link `boot/foo' => `foo': Invalid cross-device link Check the errno [root@dhcp-9-42 mountpoint]# cat /usr/include/asm-generic/errno-base.h | grep EXDEV #define EXDEV 18 /* Cross-device link */ So, change the status to verified. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
