Unable to extract the downloaded file HCM-920-UPD-022-OVA_12of15.zip

While deploying DKP for Peoplesoft HCM 9.2 PUM Image#22, I encountered this error several times and tried several times and all failed.
Lastly, I logged into the Oracle Linux using root when the screen showing that pressing any key to continue.
By using df - hl command, I found that the storage of /dev/sdb1 is all used.
/dev/sdb1              49G   49G   0G  100% /opt/oracle/psft/dpk

Also, I found that all the HCM-920-UPD-022-OVA_xof15.zip files are under that folder. I had already extracted all those files under DKP_INSTALL folder manually before I import the ova file. Seems those files don't need to be in that folder.

I deleted all these HCM-920-UPD-022-OVA_xof15.zip files in DKP_INSTALL folder(there are backups in another folder). Now, the deployment is in progress.

Note, don't leave the HCM-920-UPD-022-OVA_xof15.zip files under DKP_INSTALL folder if you have them before you extracted them.
