resize issue about ceph-iscsi-cli HOT 7 CLOSED

@pcuzner Do not worry about disabling resize. The PRs:

ceph/ceph-iscsi-config#43
ceph/ceph-iscsi-config#27
open-iscsi/tcmu-runner#346

should fix all the known issues except the one where a initiator could race with us. It could be rescanning the size on each path at the same time we are updating and the initiator could end up with a mismatch on different paths. For that race you currently have to initiate manual resize on the initiator side.

Resize is broken right now.

On newer kernels it will work, but can cause hangs if the device is blacklisted.

On older kernels you will not see the size updated like above.

If you reboot the gws then the new size would take affect and the initiator would see it when the device is rescanned.

@mikechristie should we disable resize for now to avoid issues with people testing?

@mikechristie which kernel version works? or which target patch should I apply in kernel?

from ceph-iscsi-cli.

@pcuzer, yeah it is probably best to just disable for now.

@vatelzh, there is no fix done yet. For my comment about it working I should have been more specific. If you use the kernel and patches listed in the tcmu-runner 1.3.0rc4 release notes then it would work under really specific conditions. It is not safe to use right now.

@mikechristie Ok. I have a patch for cli start up times, so once that's confirmed by vatelzh, let's get that merged, and then I'll drop resize out of the cli and api in a subsequent PR.

Resize should be working in the current release. Closing this issue.
