Re: iscsi resize -vmware datastore cannot increase size

[Steven Vacaroaia <stef97@xxxxxxxxx>]

I noticed this 

[vob.iscsi.discovery.login.error] discovery failure on vmhba64 to 10.10.35.202 because the target returned a login status of 0201.

A restart of rbd services will require reentering chap credentials on targets ?

Did you rescan the LUNs in VMware after this latest resize attempt?
What kernel and tcmu-runner version are you using?
