So i have previously opened chr vmdk in VMware player and changed size to 2gb, it all works fine in VMware player i can upload files inside CHR. But when i use that vmdk in ESXI it all works fine i can open that CHR via winbox and it shows 2GB in resource but when ever i want to upload my backup file of 100mb it does not allow me, ESXI always show error that it does not have enough of free space, what am doing wrong here, is anyone kind to assist me with this i would really appreciate it?! Thanks

When increasing disk sizes for KVM Virtual Machines it's generally necessary to resize the file system with something like resize2fs. I imagine the same applies to the CHR, however I dont know if it has the appropriate tools built in.

Does it make any difference for ESXI ?
