I have a Centos 7 install using EXT4 on LVM. Its running as a VM inside KVM. Issue I have run into is that fstrim does not work due to the LVM. Without fstrim snapshots have gotten huge. Is there a way convert it from LVM to non-LVM without a complete reinstall?

Hi All I'm trying to setup my LVM thin pool to support discards so that the pool can reclaim space even if the underlying device doesn't support trim. It is my understanding that all thin pools should support trim even if the underlying device doesn't. (please correct me if I'm wrong here) I have one centos server that does support trim and everything is working correctly but any

I just ordered a new machine that's destined to become a Centos 6 application server for a publishing company, and decided to get one with a 40GB SSD as well as a standard hard drive. I'm thinking that I can put most of the operating system on that drive and have the home directories and whatnot on the regular hard drive. Are there any pitfalls lying in wait for an unwary person like me

CDE can actually be installed on Centos 7 through yum: https://copr.fedorainfracloud.org/coprs/dcantrel/cde/ Just install the repo file and "yum install cde" That gives you CDE version 2.3. I installed it on an VirtualBox image that I use for

I mentioned here the other day that I was planning to set up a Centos 6 system using a SSD for the system drive and a regular hard drive for a data drive. My plan is to have everything that doesn't change (much) on the SSD, such as /boot, /lib, /bin and so on. I want to put /tmp and /var and /home on the regular hard drive. Now that I'm at the stage of actually setting this up I have

I still get the "the discard operation is not supported" fstrim error when the LVs are set to "nopassdown" Seems that when I use ext4 the fstrim reports that it worked but the LVs Data% does not decrease after the fstrim. xfs just throws the error. I've also been looking at the output of lsblk -D # lsblk -D NAME DISC-ALN DISC-GRAN DISC-MAX DISC-ZERO xvdb

My guess? The passthrough is causing the error when the command passes through to the actual device, which doesn't support Trim. I don't know how it actually works, but you can try to poke it with this stick: copy a large file to this LV. Check the LV with lvdisplay. Delete the file. Fstrim. Lvdisplay. Now compare the two lvdisplay results. It should show the PEs used are less after

Hi, I just recently read a post about SSD triming (discard vs fstrim): ?http://www.howtogeek.com/176978/ubuntu-doesnt-trim-ssds-by-default-why-not-and-how-to-enable-it-yourself/So far I used discard on all my SSDs. Now I am wondering if it is really worth it to switch them all to a crontabed fstrim... Anyone made the switch yet? Thx, JD

if you look in /lib/systemd/system runlevel1.target is a link to rescue.target I think the command is systemctl isolate rescue.target (or runlevel1.target if you prefer) On Sun, Nov 23, 2014 at 3:15 PM, Frank Cox <theatre at melvilletheatre.com> wrote: > On Sun, 23 Nov 2014 12:02:17 -0800 > Edward M wrote: > > > Centos 7 runs systemd > > This actually bring up

As long as you have the DisplayPort connection on your computer and you have the proper cable to connect it to the monitor then it's no trouble. I had been using dual DP monitors on my last work machine. Also, note that sometimes the PC end is normal DisplayPort but sometimes it has a mini DisplayPort connection. Just get the right cable and it should be as simple as HDMI. On Jan 28, 2015

that diff has /misc/misc/ in the second compare argument. Not sure if thats the exact command you have been entering or if you retyped it. If that is a good path or is rsync creating new ?misc? folders inside your original misc folder? -- Jeremy Thompson Sports Warehouse Inc. jeremy at warehousesports.com > On May 1, 2015, at 10:10 AM, Frank Cox <theatre at melvilletheatre.com>
