Greetings,
Happy old year! ;-)
Running XFS on Ununtu 10.04 LTS, I have noticed more warnings with XFS dump the longer the system has been up. A reboot cuts down on the number of warnings xfsdump encounters. An example run of
xfsdump is as follows:
/usr/sbin/xfsdump: using file dump (drive_simple) strategy
/usr/sbin/xfsdump: version 3.0.4 (dump format 3.0) - Running single-threaded
/usr/sbin/xfsdump: level 0 dump of ldslnx01:/srv
/usr/sbin/xfsdump: dump date: Sat Dec 31 15:25:42 2011
/usr/sbin/xfsdump: session id: b56b3cd7-30d6-44b4-a8a4-e131ee70b60d
/usr/sbin/xfsdump: session label: "data"
/usr/sbin/xfsdump: ino map phase 1: constructing initial dump list
/usr/sbin/xfsdump: ino map phase 2: skipping (no pruning necessary)
/usr/sbin/xfsdump: ino map phase 3: skipping (only one dump stream)
/usr/sbin/xfsdump: ino map construction complete
/usr/sbin/xfsdump: estimated dump size: 115786343168 bytes
/usr/sbin/xfsdump: WARNING: no media label specified

/usr/sbin/xfsdump: ending media file
/usr/sbin/xfsdump: media file size 115563111376 bytes
/usr/sbin/xfsdump: dump size (non-dir files) : 115472209824 bytes
/usr/sbin/xfsdump: dump complete: 4099 seconds elapsed
/usr/sbin/xfsdump: Dump Status: SUCCESS
Could someone please explain what is going on, and why a freshly rebooted system would result in less / no errors?
Sincerely,
