RHEL7 - xfsdump fails with error "ERROR: media contains valid xfsdump but does not support append"
Issue
-
Currently deploying several urgent RHEL7 production systems.
-
On RHEL6 I had written a script to execute a weekly compressed ext4 filesystem dump of the core OS filesystems to file to aid in OS recovery.
/sbin/dump -0uz -f /dump/root.dmp.gz /
- Am trying to replicate this for xfs filesystems on RHEL7 without success. Would have thought the following would work
xfsdump -F -l 0 -f /appl/var.xfs_dmp /var
- However it produces the following errors. There also is no detail around using compression when writing to file.
