Persistent reading from disk of mysql process on a stopped slave

[tbabut]

Hi,

I don’t know if this is bug, but we haven’t seen this behaviour before.

We are running a Percona MySQL Slave Server 5.5.28-29.1-log on a Debian Squeeze 6.0.6 (64-Bit) system. When we start the MySQL daemon (without restoring the dumped pool buffer) or stop the slave process the MySQL process is permanently reading from disk:

iostat -kx sda 3Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %utilsda 0,00 0,00 121,67 0,00 1946,67 0,00 32,00 0,98 8,09 8,07 98,13

This slave is a backup server and there are no selects running on this host at all.

The MySQL config file:

What is MySQL doing here or how can I find out?

Thanks in advance.

Perhaps try “strace -c -p 1779”, or for more detail “strace -Tttf -p 1779”? Note that strace can occasionally cause breakage, which may be less worrisome given that this is a slave.
