Prism Central - home partition does not expand to 50Gb

Currently running PrismCentral pc.2021.3.0.2

After upgrading to this version, the /home partition is supposed to expand to 50gb from 40gb.  This unfortunately did not happen.

I found KB9525, and tried to run this command to manually expand the partition:

sudo python /usr/local/nutanix/bootstrap/bin/ --skip_end_sector_validation

That didn’t succeed in expanding the /home partition (which was sitting at 91% utilisation)

In the pc_config_home_partition.log file, I found this error:

:178 BLKRRPART: Device or resource busy
sfdisk: The command to re-read the partition table failed.
Run partprobe(8), kpartx(8) or reboot your system now, before using mkfs

I ran partprobe, didn’t help

kpartx requires parameters, and I wasnt sure what inputs to provide, so I didn’t run that

I did reboot Prism Central, but that didn’t help either, except it did somehow reduce disk utilisation of /home to 76% from 91%.  Still couldn’t expand the disk though

Anyone faced a similar situation, or have any insights?

Hi Mike,

Thanks Maaz.


I did get the help I needed from Nutanix Support (I was originally hoping it would be a simple fix that someone here could share).
