PXC on Debian fails to start with datadir containing underscore

[Taras]

Looks like mysqld_get_param() inside the Debian init script replaces '_' with '-' using tr '_' '-'. This causes sidk space check to fail using df

df: `/mnt/mysql/mysql-data/.': No such file or directory
df: no file systems processed
[FAIL] /etc/init.d/mysql: ERROR: The partition with /mnt/mysql/mysql-data is too full! ... failed!

OS is Debian 7

This is a regression from https://bugs.launchpad.net/percona-xtradb-cluster/+bug/1208865

It (tr) was only meant for the key and not the value,

Following should fix it.

@Taras,

You can use the debs here: http://www.percona.com/downloads/TESTING/Percona-XtraDB-Cluster/5.5.33-23.7.6/release-5.5.33-23.7.6/496/ till they are pushed to release repo in sometime.

[Raghavendra D Prabhu (raghavendra-prabhu)]

The fixed debs are in release state now, apt-get update should fix this (though during stop while update it still calls the older init script).
