mysql - mysqldump: Got errno 32 on write

Question

I used this script for years on my VPS. And it's still working.

DBLIST=`mysql -uroot -pROOT_PASSWORD -ANe"SELECT GROUP_CONCAT(schema_name) FROM information_schema.schemata WHERE schema_name NOT IN ('information_schema','performance_schema')" | sed 's/,/ /g'`
MYSQLDUMP_OPTIONS="-uroot -pROOT_PASSWORD --single-transaction --routines --triggers"
BACKUP_DEST="/home/backup/db/"
for DB in `echo "${DBLIST}"`
do
    mysqldump ${MYSQLDUMP_OPTIONS} ${DB} | gzip > ${BACKUP_DEST}/${DB}.sql.gz &
done
wait
tar -czvf /home/backup/db2/`date +\%G-\%m-\%d`_db.tar.gz ${BACKUP_DEST}

Now I'm moving to another hosting. I 'm trying to use the same script (of course I changed ROOT_PASSWORD with the new credentials) but I don't know why I get this:

mysqldump: Got errno 32 on write
mysqldump: Got errno 32 on write

OS error code  32:  Broken pipe

So errno 32 is "broken pipe". You're piping the mysqldump output to gzip , so this means gzip terminated prior to mysqldump finished. Could e.g. be because your disk is full, or gzip surpassed any max CPU time/usage your host has in place.
