reduce disk size of VCSA

[TomKalabis]

Hi,

i have upgraded vcsa 6.7 from 6.5u1 and my vdmk8 have abou 514 GB, but only 1 % is used, now my vcenter size is about 800 GB:

root@vcenter [ ~ ]# df -h

Filesystem                                Size  Used Avail Use% Mounted on

devtmpfs                                  4.9G     0  4.9G   0% /dev

tmpfs                                     4.9G  800K  4.9G   1% /dev/shm

tmpfs                                     4.9G  696K  4.9G   1% /run

tmpfs                                     4.9G     0  4.9G   0% /sys/fs/cgroup

/dev/sda3                                  11G  5.7G  4.4G  57% /

tmpfs                                     4.9G  1.4M  4.9G   1% /tmp

/dev/sda1                                 120M   31M   81M  28% /boot

/dev/mapper/core_vg-core                   25G   44M   24G   1% /storage/core

/dev/mapper/log_vg-log                    9.8G  1.3G  8.0G  14% /storage/log

/dev/mapper/db_vg-db                      9.8G  260M  9.0G   3% /storage/db

/dev/mapper/dblog_vg-dblog                 15G  534M   14G   4% /storage/dblog

/dev/mapper/seat_vg-seat                  542G  660M  514G   1% /storage/seat

/dev/mapper/netdump_vg-netdump            985M  1.3M  916M   1% /storage/netdump

/dev/mapper/autodeploy_vg-autodeploy      9.8G   33M  9.2G   1% /storage/autodeploy

/dev/mapper/imagebuilder_vg-imagebuilder  9.8G   23M  9.2G   1% /storage/imagebuilder

/dev/mapper/updatemgr_vg-updatemgr         99G  1.8G   92G   2% /storage/updatemgr

/dev/mapper/archive_vg-archive             50G  5.1G   42G  11% /storage/archive

is there any way to reduce /dev/mapper/seat_vg-seat  (disk8) size?

STORAGE USAGE

829.71 GB

You'd have to go through the (moderately painful) process of adding a new disk, moving data, changing the mount point, and removing the old disk from the vCSA. There's no supported way to do it otherwise, AFAIK.

Hi

as daphnissov​ said there is documented way to achieve this however I was reaserching on same and found this one which is related from VCSA 6.5

I see that storage/seat is used for purpose :  Stats, Events, Alarms and Tasks (SEAT) directory for VMware Postgres

I dont see specific blog or article to resize this particular partition but found a blog which talks about a different partition one among them , you cna check this :

https://www.virtuallyghetto.com/2016/11/updates-to-vmdk-partitions-disk-resizing-in-vcsa-6-5.html

NOTE: Make sure to take back up before you perform anything in worse scenario.

Please consider marking this answer as correct and helpful if this helps you.

Did you use "Thick Provisioning" while deploying (upgrading) the vCSA?

Instead of modifying the guest OS disk size/partition size, it may be an option to use Storage vMotion to convert the disks to "Thin Porovisioned".

yes André,

i use "thick provisioning" while i upgrading vcsa.

ok, i will try it.

I worked with customer one of my customer recently and was able shrink the disk.

Here are the steps:

You will need to stop all services before you follow the process:

• Copy the existing data from /storage/seat to /storage/core (or any volume) where we have 50 GB free space.
• Deploy a new vCSA of the same build and expand /storage/seat to 100 GB.
• Unmount /storage/seat from existing vCSA and mount /storage/seat from new vCSA to the existing one.
• Post this you will have to copy the data from /storage/core to /storage/seat and start services.

Alternatively you can try using VMware converter. I have not tried this though.
