Hi, The best and safe way to do that is by adding another vHD as a new PV to your root_vg and then grow your LV. No need to stop services, shutdown or reboot the VM; if it's in prod environment.

Hello all,
In your view, what is the most reliable and safe way to increase an LV housing the root filesystem of a Centos 6 VM. I am thinking either
growing

PV to the VM, or perhaps migrating the whole FS to a new virtual disk.
Any input on how best to proceed would be appreciated.
Dumb question: why do you need a larger root filesystem?
First, how big is root? And if this is for stuff under, say, /var/www, I'd make a separate logical drive/partition, and mount that, rsync everything from /var/www to that, then shut down the web, and remount the new filesystem on /var/www.
Root, itself, doesn't need to be huge. We're using 500G, and seriously considering making it 125G in the future, with data, or web stuff, is on a separate partition, so when there's a sudden explosion of data, / is safe.
markMark,
Thanks for your input.
Well, we are talking much smaller scale here (only about 30 GB at present, planning to roughly double it).
I agree with you that it is best to keep usage/operational data outside of root - but it just historically so happened that this is how we do things. So for now this is the task and I need to perform it somehow.
Cheers,
Boris. _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
