Fix mariadb recover seqnum regex
Browse files Browse the repository at this point in the history 
Regex used to find the recover seqnum partition is not
returning the real num id rather a None.
Task fails due seqnum[0] is not iterable.

hello,
shell: tail -n 200 /tmp/mariadb_tmp.log | awk -F" " '$0~/Recovered position/{print $NF;exit;}' | awk -F":" '{print $1}'
did this caught the uuid not the seqno?
tail -n 200 /tmp/mariadb_tmp.log | grep Recovered | tail -1 | awk '{print $7}' | awk -F'\n' '{print $1}' | awk -F':' '{print $2}' is useful for me.
if the mariadb restart several times, tail -n 200 may get old&wrong seqno, tail -1 is necessary to get the new&right seqno.
