Upgrade fails with Not enough disk space

[larstr]

Hi,

I'm using vcsa-cli-installer and trying to upgrade from vCenter 6.5U1 to 6.7U1. It is however failing:

2019-06-03 09:01:41,922 - vCSACliInstallLogger - INFO - ================ [FAILED] Task: Running precheck: RecommendOrCheckExportDirTask execution failed at 09:01:41 ================
2019-06-03 09:01:41,928 - vCSACliInstallLogger - DEBUG - Task 'Running precheck: RecommendOrCheckExportDirTask' execution failed because [Not enough disk space on '/' for exporting source data 3.99 GB including migrate set 'core' in export_dir '/storage/updatemgr/temp'.], possible resolution is ['/storage/updatemgr' has sufficient space to accommodate source export data. Provide this as export folder in source_vc.vc_vcsa.export_dir field in template.]

In the vc_vcsa section of my config file I have specified:

"export_dir": "/storage/updatemgr/temp"

The disk space of my source vCenter is as follows:

Filesystem                                Size  Used Avail Use% Mounted on
devtmpfs                                  7.9G     0  7.9G   0% /dev
tmpfs                                     7.9G   20K  7.9G   1% /dev/shm
tmpfs                                     7.9G  688K  7.9G   1% /run
tmpfs                                     7.9G     0  7.9G   0% /sys/fs/cgroup
/dev/sda3                                  11G  7.2G  3.0G  72% /
tmpfs                                     7.9G  1.5M  7.9G   1% /tmp
/dev/sda1                                 120M   28M   87M  25% /boot
/dev/mapper/db_vg-db                      9.8G  5.9G  3.4G  64% /storage/db
/dev/mapper/netdump_vg-netdump            985M  1.3M  932M   1% /storage/netdump
/dev/mapper/seat_vg-seat                   25G  8.8G   15G  38% /storage/seat
/dev/mapper/log_vg-log                    9.8G  4.7G  4.6G  51% /storage/log
/dev/mapper/dblog_vg-dblog                 15G  2.5G   12G  18% /storage/dblog
/dev/mapper/core_vg-core                   50G   52M   47G   1% /storage/core
/dev/mapper/updatemgr_vg-updatemgr         99G  2.8G   91G   3% /storage/updatemgr
/dev/mapper/imagebuilder_vg-imagebuilder  9.8G   23M  9.2G   1% /storage/imagebuilder
/dev/mapper/autodeploy_vg-autodeploy      9.8G   34M  9.2G   1% /storage/autodeploy

So my /storage/updatemgr has 91G of available disk space which should be more than enough.

Not sure what the easiest method would to proceed here?

So I crawled the file system and deleted non-critical files and now the upgrade is running.

I wish the root file system had been larger or that the export_dir setting had worked as I thought it would.

Resizing the root file system is not supported by VMware and the unsupported method looks spooky.

Out of curiosity, did you create the temp folder prior to running the migration?

I did an upgrade a few days ago (from the GUI), and specified "/storage/updatemgr" without a sub-directory, which worked.

André,

I think I created the temp directory. I have a pile of vcenters and pscs to upgrade so I'll give it another try the next time I encounter this problem.

I've the same problem.  "export_dir": "/storage/updatemgr/migration" setting on .json file didn't work. I created "migration" folder before the upgrade.

The log shows:

Running precheck: RecommendOrCheckExportDirTask execution failed

Error message: Not enough disk space on '/' for exporting source data 19.34 GB

including migrate set 'all' in export_dir '/storage/updatemgr/migration'.

Any idea how to point exporting source data to "/storage/updatemgr/migration" ?

Can you provide some more details on how you crawled the file system?  I have a VCSA that is doing this for the current 8.0.0-21457384 patch.
