let’s say the cluster name is “mynamran” and the shared storage device is mapped to /dev/mapper/mpath0
so the command to create GFS2 partition is as below :
mkfs.gfs2 -p lock_dlm -t mynamran:gfs2 -j 8 /dev/mapper/mpath0 |
then to test mount it .. to a /gfs2
mount -o acl -t gfs2 /dev/mapper/mpath0 /gfs2 |
any node which is members of “mynamran” cluster will be able to mount this
storage simultaneously ..
some other tools to test
gfs2_tool list
gfs2_tool df |
woohoo..!
it shall however.. un-mounted before machine goes off.
hence.. is recommended putting this into /etc/fstab
current working setting is as below
/dev/mapper/mpath0 /gfs2 gfs2 defaults,noatime,nodiratime 0 0 |
there option to actually mount the GFS2 partition via cluster suite..
but that probably for just the active node .. which somehow defeat the purpose.. of enabling it to actually having multiple node
accessing same storage.. without NFS.. 🙂
the step to remove old plesk before can start install a new
but it is preferable to have a complete system restore..
*** somehow . to wait for sys-admin to do thing to you.. ah.. a lil’ bit fu*ked thing.. why not ***..
as root..
1. yum remove psa-*
2. yum remove httpd
3. rm -rf /var/httpd -R
4. rm -rf /usr/local/psa -R
5. rm -rf /var/www/vhosts -R
6. service mysqld stop
7. If don’t know the root pass for myql .try this as root :
mysqld_safe –skip-grant-table
6. mysql -uroot
i. drop database psa
ii. drop database phpmyadmin_14813SHFF <-- some serial here can see using show databases; iii. drop database horde; iv. drop database sitebuilder; v. and any other thing .. except test and mysql; vi. may have to reset pass for root to blank ... if u want to delete other user than root in mysql use mysql; delete * from user where User!='root'; update user set Password=PASSWORD('') where User='root'; may be need to add the admin user with pass setup. and with all priv here. insert into user (Host,User,Password) values ('localhost',admin,PASSWORD('something-default-here')); then have to grant.. all the privilege. to the admin then remove mysqld. yum remove mysql. ***.. after that may proceed with re-installation process. note i did'nt remove any other user created before.. such as qmail.. bla..bla.. because we are going to re-install .. then.. ./psa_installer_v3.1.2_build070321.17_os_CentOS_4_i386 answer all question.. wait.. till finished.. hopefully no problem.. may be need to flush the firewall services iptables restart.. then can access to https://server.name.com:8443/
you should see the login screen..
wahaha..
