is there any way to reduce /dev/mapper/seat_vg-seat (disk8) size?
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 :
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".
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:
Alternatively you can try using VMware converter. I have not tried this though.
