aking LVM snapshots as a mean of backing up MySQL is rather simple, as can be described here. However, if you are into security, you would strive to grant minimal permissions for the action to the MySQL user. Per MySQL Documentation, the required privileges is “RELOAD”. That should be enough, granted on *.*, of course.

I would like to start with a declaration – I would prefer not to use ACFS for a stand-alone system. It binds the “normal” order of startup and mounts to the cluster. Not only that – but while until version 12.1, RAC stand alone had a built-in service for ACFS, this is no longer the…
Just to remember, there is an explanation here, from which the following directive can be taken: (cpio -id; zcat | cpio -id) < /path/to/initrd.img Related posts: Extracting multi-layered initramfs Rapid-guide – Updating RedHat initrd Replace Old NTP Commands With “chronyc” on a Modern Linux Extracting/Recreating RHEL/Centos6 initrd.img and install.img Powered by YARPP.
Putty has announced that they will not allow automatic import of host key. You should press the damn ‘y’ yourself, or else, you will fail. A quote from their FAQ says: “A.2.9 Is there an option to turn off the annoying host key prompts? No, there isn’t. And there won’t be. Even if you write…
Boel initrd files are actually compressed cramfs files. This is a menuscript for authoring and modifying these files, if needed. Assume the file in question is /tftpboot/install-initrd-i386.img: cp /tftpboot/install-initrd-i386.img /tmp/ cd /tmp/ gzip -S .img -d install-initrd-i386.img mount -o loop install-initrd-i386 /mnt mkdir initrd cd /mnt/ tar cf – . | (cd /tmp/initrd/ ; tar…
I’ve been to Hostopia today. The land of hosting servers. I’ve had an emergency job on one Linux server, due to a mistake I’ve made. It appears that the performance hindrance of using raid0 instead of raid1 (Centos/RH default raid setup is raid0 and not raid1, which led me to this mistake) for the root…
A nice and informative note about how to obtain OracleASM attributes, including “hidden attributes” can be found here. Including the special attribute “_rebalance_compact” which affects the post-rebalance ‘compact’ ASM operation, when altering DiskGroups (per-DiskGroup, of course). Just a reminder about this specific attribute – when ASM performs rebalance operation (adding or dropping disks) it attempts…
