Resize errors

2011-06-13 10:47:30 	Yes 	10.30.113.153 	0.0000 	Error executing [lvcreate -L45G -s -nS65G4U-BACKUP-20110613T144729 /dev/LVM/S65G4U] [5] ( Insufficient free extents (28) in volume group LVM: 1440 required )

Always check with DAN BURKE first to make sure it is ok to do this

The fix for this would be the following.

lvdisplay -C

this will provide the following type of output.

[root@host411 ~]# lvdisplay -C
 LV                            VG   Attr   LSize   Origin Snap%  Move Log Copy%  Convert
 28K4MS                        LVM  -wi-ao 150.00G
 82P51W                        LVM  -wi-ao 150.00G
 8GZQQ4                        LVM  owi-ao 150.00G

 S216PX                        LVM  -wi-ao 150.00G

Now you only want to remove the ones that have the Snap% colum at 100.

cd /dev/mapper/
for i in (lvm volume to remove)*; { dmsetup remove $i } 
lvremove (lvm volume to remove)*

(01:00:25 PM) mshooltz: i have a new provisioning error that I havent come across before, I am assuming that it means there was not enough space on the server the backup was supposed to go on for a resize image but i am not sure. (01:00:27 PM) mshooltz: Error executing [lvcreate -L45G -s -nS65G4U-BACKUP-20110613T144729 /dev/LVM/S65G4U] [5] ( Insufficient free extents (28) in volume group LVM: 1440 required ) (01:00:41 PM) mshooltz: https://billing.int.liquidweb.com/mysql/content/admin/account/provision/?accnt=182095 (01:01:05 PM) dburke: yeah, just need to cleanup the snapshots and try again (01:01:14 PM) dburke: there's a fix coming for it (01:01:26 PM) mshooltz: ok got a guide i can use to clean them up? (01:02:49 PM) dburke: done... I usually do a bunch of these every morning, I just haven't gotten to it yet today (01:02:57 PM) mshooltz: oh ok thanks (01:03:46 PM) mshooltz: ok thanks, can you let me in on how you did that? (01:04:12 PM) dburke: cd /dev/mapper/ for i in S65G4U-BACKUP-20110*; { dmsetup remove $i }

lvremove /dev/LVM/S65G4U-BACKUP-20110*

(01:04:56 PM) mshooltz: wow that is all there is to it? log into the parent and run those? (01:05:15 PM) dburke: I don't really want other people to get into the habit of doing it, because in case the fix doesn't work, I might not be aware of it because people are fixing it manually (01:05:46 PM) dburke: but yeah, that's pretty much it (01:06:05 PM) dburke: well, you need to run "lvdisplay -C" and only do that on FULL snapshots (01:06:19 PM) mshooltz: well i wont hand it out to others, and I will check with yall before attempting (01:06:26 PM) dburke: ok thanks
