Recommended partitioning of a vm for EFA 4

[webguyz]

Downloaded the EFA4 iso and it installs Centos and wants to know how to partition it. Not a big Linux guy so looking for the best way to do this for a Hyper-v 100gb VM.

Thanks!

Good question!

I just did a default install the other day and it basically made 2 50GB partitions managed by lvm

I'm not actually happy about that, so I'm thinking of reinstalling.

My own preference is to just set it as a single 100GB partition mounted under / without using LVM.

Why? Well, it's a VM and I can increase the disk size or add disks as necessary. As long as I'm backing up my VM properly, I should be ok. Also, I'll have less of a problem filling one large partition rather than 2 smaller ones.

That's not the normal or recommended practice, but I find it convenient.

I looked at eFa's v3 VM.

My v4 got a 100GB disc.
Partitioning:
1GB /boot (OS default)
200MB /boot/efi (OS default)
8GB Swap (OS default)
16GB / (double of v3)
75GB /var (all that's left)

Code: Select all

[root@efa4 ~]# df -h
Filesystem                    Size  Used Avail Use% Mounted on
devtmpfs                      3.9G     0  3.9G   0% /dev
tmpfs                         3.9G     0  3.9G   0% /dev/shm
tmpfs                         3.9G   17M  3.9G   1% /run
tmpfs                         3.9G     0  3.9G   0% /sys/fs/cgroup
/dev/mapper/centos_efa4-root   50G  2.4G   48G   5% /
none                          3.9G     0  3.9G   0% /var/spool/MailScanner/incoming
/dev/sda1                    1014M  166M  849M  17% /boot
/dev/mapper/centos_efa4-home   42G   33M   42G   1% /home
tmpfs                         799M     0  799M   0% /run/user/0

I'm going to reinstall, do a custom partition layout, no lvm, small /boot partition, large / partition.

If space ever becomes an issue I'll just add a new disk and mount is appropriately which will be easy to do since I'm running efa as a virtual machine.

[edit] For what it is worth, this is the partitioning of my EFA v3 installation on a 40GB disk

Code: Select all

[root@efa ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_00-lv_root
                      7.8G  5.3G  2.2G  72% /
tmpfs                 3.9G     0  3.9G   0% /dev/shm
/dev/sda1             485M  275M  185M  60% /boot
/dev/mapper/vg_00-lv_tmp
                      976M   11M  914M   2% /tmp
/dev/mapper/vg_00-lv_var
                       30G   19G   11G  64% /var
none                  3.9G  936K  3.9G   1% /var/spool/MailScanner/incoming
[root@efa ~]# fdisk -l

[edit 2] and this is my new efa4 disk layout

Code: Select all

[root@efa4 ~]# df -h
Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        3.9G     0  3.9G   0% /dev
tmpfs           3.9G     0  3.9G   0% /dev/shm
tmpfs           3.9G  8.9M  3.9G   1% /run
tmpfs           3.9G     0  3.9G   0% /sys/fs/cgroup
/dev/sda2        91G  1.2G   90G   2% /
/dev/sda1       2.0G  131M  1.9G   7% /boot
tmpfs           799M     0  799M   0% /run/user/0
