xbstream sometimes fails while extracting
I collected a large streaming backup over SSH which was written to a file (named 20120406_
When extracting the file, I found xbstream intermittently fails to read from the file. The error is:
The backup command was:
innobackupex --user=$USER --password=$PASS --compress --compress-
STDOUT was piped over SSH and written to the .xbs file.
The extraction command was:
xbstream -x -v < ../20120406_
This appears to be a bug in xbstream, not corrupt data. The offset was different every time the message appeared, and eventually the file extracted without any error, creating all the expected files.
Platform is Debian Squeeze x64 using the xtrabackup dotdebs from percona.com
