| 22:04.08 | Technoviking | eightyeight: sorry, been away from my terminal and IRC all day dealing with gremlins |
| 22:04.23 | eightyeight | fun |
| 22:05.18 | Technoviking | CRAC unit down in datacenter, Oracle DB borked for no apparent reason, sigh.... |
| 22:05.41 | eightyeight | :) |
| 22:06.11 | herlo | eightyeight: oh, okay |
| 22:07.07 | eightyeight | Technoviking: basically, with water in the bucket, if you want to make your bucket smaller, you need to displace some water first |
| 22:07.23 | eightyeight | Technoviking: so, resize2fs the volume to the size you want, then lvreduce the volume |
| 22:07.43 | eightyeight | Technoviking: ext2/3/4, afaik, doesn't allow online shrinking, so you'll have to take it offline |
| 22:07.56 | Technoviking | ok |
| 22:08.06 | eightyeight | also, you'll need to run an 'e2fsck -f' on the fs before you shrink (it will tell you if you don't) |
| 22:08.11 | eightyeight | so: |
| 22:08.52 | eightyeight | e2fsck -f /dev/volume/lv1; resize2fs /dev/volume/vd1 40G; lvreduce -L 40G /dev/volume/lv1 |
| 22:08.56 | eightyeight | will work for shrinking |
| 22:09.18 | eightyeight | then for growing the other, you need a bigger bucket to hold the displaced water, so you need to grow the volume first, then add the water |
| 22:09.37 | eightyeight | lvextend -L +10GB /dev/volume/lv2; resize2fs /dev/volume/lv2 |
| 22:10.10 | eightyeight | (+10G being whatever you had from your displacement of shrinkage- also, you don't need to e2fsck when growing the fs, and it doesn't need to go offline) |
| 22:10.20 | eightyeight | Technoviking: make sense? |
| 22:10.39 | Technoviking | yes, just read the man pages also as you go |
| 22:10.45 | eightyeight | nods |
| 22:11.23 | eightyeight | there is a tool that will do the filesystem changes and volume changes all rolled up into one, but i forget what it is |
| 22:12.25 | Technoviking | eightyeight: someone told me RedHat has a graphic tool also, but those always bite me in the ass |
| 22:12.46 | herlo | system-config-lvm ?? |
| 22:12.57 | herlo | but that's not related to resize2fs |
| 22:13.10 | herlo | afaik, the only tool that is a gui that might do that is gparted |
| 22:13.12 | eightyeight | that's the red hat gui, but it's not the tool i'm referring to |
| 22:13.20 | eightyeight | and it's cli |
| 22:13.25 | eightyeight | hold please, i'll find it |
| 22:22.10 | eightyeight | fsadm |
| 22:24.44 | Technoviking | is it install by default in RHEL? |
| 22:24.52 | eightyeight | so, really you'd want 'fsadm -l' seeing as though you're working on lvm |
| 22:25.02 | eightyeight | yes. it's part of the lvm2 package |
| 22:25.25 | eightyeight | there's a manual on it |
| 22:25.37 | Technoviking | cool, thanks for the info |
| 22:25.40 | eightyeight | np |
| 22:25.53 | Technoviking | I have done this once, but not for a long while |
| 22:25.58 | undertakingyou | eightyeight: nice sly RTM there. |
| 22:26.06 | eightyeight | heh |
| 22:26.17 | undertakingyou | ;) |
| 22:26.51 | eightyeight | there's a manual on it for rhel, but not for debian |
| 22:28.39 | eightyeight | the trouble with shrinking logical volumes, is getting the filesystem to match bit-for-bit |
| 22:29.06 | eightyeight | i used to shrink below what i wanted, gave the volume the size i needed, then resized the fs back up to fit the volume |
| 22:29.31 | eightyeight | fsadm will do everything for you, even matching the fs to the volume bit-for-bit |
| 22:32.18 | Technoviking | the good thing is if I blow the server by accident, it is not a big deal, justa redhat re-install |
