I have recently upgraded to XCP 1.6 (clean install and VM export/import) but I
am finding that archive element of VM Protection Policy is regularly failing
with error 'Internal error: Failure ("Compression via zcat failed: exit code
1")'
I have several Protection Policies which archive to a nfs share, some archive
every time some just weekly but this behaviour seems to be consistent for them
all. Typically only one completes. I have looked in messages and
xensource.log and whilst I can see the export being started I cannot find
anything more concrete on reasons for failure
Example
Dec 18 09:04:32 tottington xapi: [ info|tottington|7220235 UNIX
/var/xapi/xapi||cli] xe vm-export password=null
vm=cfc3a8b4-8630-c362-3ab1-96e6bddec71d
filename=/tmp/4ad35422-bd7c-499b-af64-1c5a206e50b9/WinXP-1e117f74-93b0-86/20121218-0904.xva
compress=true username=root
I have also manually started the task (same syntax) and whilst the job started
it failed within 15 mins 'INTERNAL_ERROR: [ Unix.Unix_error(56, "write", "") ]'.
I then manually started an export via XenCenter which ran to completion with no
issues and so much quicker (36 mins vs 4hrs and still going)! (one difference
is via cifs rather than nfs share to same remote volume)

Jon
