Joshua Boniface b3a75d8069 Use post instead of get on initialize 2020-04-06 15:05:33 -04:00
Joshua Boniface c3bd6b6ecc Add missing call into cluster initialize function 2020-04-06 14:48:26 -04:00
Joshua Boniface 5d58bee34f Add some time around noded startup/shutdown 
Otherwise, systemd kills networking before the node daemon fully stops
and it goes into "dead" status, which is super annoying.

Joshua Boniface f668412941 Don't use Requires as the dep is too hard 
Requires seems to flush on every service restart which is NOT what we
want. Use Wants instead.

Joshua Boniface a0ebc0d3a7 Add more robust requirements to pvc-flush service 2020-04-01 15:09:44 -04:00
Joshua Boniface 98a7005c1b Add significant TimeoutSec to pvc-flush service 
This will stop systemd from killing the service in the middle of a flush
or unflush operation, which completely defeats the purpose. 30 minutes
was chosen as this is a very large but still somewhat manageable value,
which should cover even a very large very loaded cluster with room to
spare.

Joshua Boniface 1e4350ca6f Properly handle takeover state in VXNetworks 
Most of these actions/conditionals were looking for primary state, but
were failing during node takeover. Update the conditionals to look for
both router states instead.

Also add a wait to lock flushing until a takeover is completed.

Joshua Boniface b8852e116e Improve handling of root disk in GRUB 
Since vdX names become sdX names inside VMs, use the same setup as the
fstab in order to map this onto a static SCSI ID.

Joshua Boniface fd80eb9e22 Ensure profile creation works with empty lists 
If we get a 404 code back from the upper function, we should create an
empty list rather than trying to loop through the dictionary.

Joshua Boniface 9d5f50f82a Implement progress bars for file uploads 
Provide pretty status bars to indicate upload progress for tasks that
perform large file uploads to the API ('provisioner ova upload' and
'storage volume upload') so the administrator can gauge progress and
estimated time to completion.

Joshua Boniface 56a9e48163 Normalize all return messages 
Ensure all API return messages are formated the same: no "error", a
final period except when displaying Exception text, and a regular spaced
out format.

Joshua Boniface e4e4e336b4 Handle invalid cursor setup cleanly

Joshua Boniface 39ce704969 Implement wait for node primary/secondary in CLI 
Use a different wait method of querying the node status every
half-second during the transition, in order to wait on the transition to
complete if desired.

Closes #72
 2020-02-19 14:33:31 -05:00
Joshua Boniface d2a5fe59c0 Use transitional takeover states for migration 
Use a pair of transitional states, "takeover" and "relinquish", when
transitioning between primary and secondary coordinator states. This
provides a clsuter-wide record that the nodes are still working during
their synchronous transition states, and should allow clients to
determine when the node(s) have fully switched over. Also add an
additional 2 seconds of wait at the end of the transition jobs to ensure
everything has had a chance to start before proceeding.

Joshua Boniface 8678dedfea Revert "Implement wait for node coordinator transition" 
This reverts commit 0aefafa7f7.

This does not work since the API goes away during the transition.
