Joshua Boniface 1023c55087 Fix bug in VM state list 2023-12-10 23:44:01 -05:00
Joshua Boniface 9235187c6f Port Ceph functions to read_many 
Only ports getOSDInformation, as all the others feature 3 or less reads
which is acceptable sequentially.
 2023-12-10 22:24:38 -05:00
Joshua Boniface 0c94f1b4f8 Port Network functions to read_many 2023-12-10 22:19:21 -05:00
Joshua Boniface 44a4f0e1f7 Use new info detail output instead of new lists 
Avoids multiple additional ZK calls by using data that is now in the
status detail output.
 2023-12-10 22:19:09 -05:00
Joshua Boniface 5d53a3e529 Add state and faults detail to cluster information 
We already parse this information out anyways, so might as well add it
to the API output JSON. This can be leveraged by the Prometheus endpoint
as well to avoid duplicate listings.
 2023-12-10 17:29:32 -05:00
Joshua Boniface 35e22cb50f Simplify cluster status handling 
This significantly simplifies cluster state handling by removing most of
the superfluous get_list() calls, replacing them with basic child reads
since most of them are just for a count anyways. The ones that require
states simplify this down to a child read plus direct reads for the
exact items required while leveraging the new read_many() function.
 2023-12-10 17:05:46 -05:00
Joshua Boniface a3171b666b Split node health into separate function 2023-12-10 16:52:10 -05:00
Joshua Boniface 48e41d7b05 Port Faults getFault and getAllFaults to read_many 2023-12-10 16:05:16 -05:00
Joshua Boniface d6aecf195e Port Node getNodeInformation to read_many 2023-12-10 15:53:28 -05:00
Joshua Boniface 9329784010 Implement async ZK read function 
Adds a function, "read_many", which can take in multiple ZK keys and
return the values from all of them, using asyncio to avoid reading
sequentially.

Initial tests show a marked improvement in read performance of multiple
read()-heavy functions (e.g. "get_list()" functions) with this method.
 2023-12-10 15:35:40 -05:00
Joshua Boniface b9fbfe2ed5 Improve fault ID format 
Instead of using random hex characters from an md5sum, use a nice name
in all-caps similar to how Ceph does. This further helps prevent dupes
but also permits a changing health delta within a single event (which
would really only ever apply to plugin faults).
 2023-12-09 16:48:14 -05:00
Joshua Boniface 7e6d922877 Improve fault detail handling further 
Since we already had a "details" field, simply move where it gets added
to the message later, in generate_fault, after the main message value
was used to generate the ID.
 2023-12-09 16:13:36 -05:00
Joshua Boniface 4003204f14 Remove bracketed text from fault_str 
This ensures that certain faults e.g. Ceph status faults, will be
combined despite the added text in brackets, while still keeping them
mostly separate.

Also ensure the health text is updated each time to assist with this, as
this health text may now change independent of the fault ID.
 2023-12-09 15:34:18 -05:00
Joshua Boniface 2bea78d25e Make all remaining limits optional 2023-12-09 13:43:58 -05:00

Joshua Boniface d1e34e7333 Store fault times only to the second 
Any more precision is unnecessary and saves 6 chars when displaying
these times elsewhere.
 2023-12-06 13:20:18 -05:00
Joshua Boniface 79eb54d5da Move fault generation to common library 2023-12-06 13:17:10 -05:00

Joshua Boniface 672e58133f Implement interfaces to faults 2023-12-04 01:37:54 -05:00
Joshua Boniface 3dc48c1783 Lower default monitoring interval to 15s 
Faults are also reported on the monitoring interval, so 60s seems like
too long. Lower this to 15 seconds by default instead.
 2023-12-01 17:38:28 -05:00
Joshua Boniface 9c2b1b29ee Add node health to fault states 
Adjusts ordering and ensures that node health states are included in
faults if they are less than 50%.

Also adjusts fault ID generation and runs fault checks only coordinator
nodes to avoid too many runs.
 2023-12-01 17:38:28 -05:00
Joshua Boniface 8594eb697f Add initial fault generation in pvchealthd 
References: #164
 2023-12-01 17:38:27 -05:00
Joshua Boniface 7cb9ebae6b Remove legacy configuration handler 
This is not going to be needed.
 2023-12-01 01:25:40 -05:00
Joshua Boniface 102c3c3106 Port all Celery worker functions to discrete pkg 
Moves all tasks run by the Celery worker into a discrete package/module
for easier installation. Also adjusts several parameters throughout to
accomplish this.
 2023-11-30 02:24:54 -05:00
Joshua Boniface 03a738f878 Move config parser into daemon_lib 
And reformat/add config values for API.
 2023-11-30 00:05:37 -05:00

Joshua Boniface 83ceb41138 Add daemon name to Logger entries 2023-11-29 15:18:37 -05:00
Joshua Boniface 2e5958640a Remove erroneous time from message 2023-11-29 15:12:41 -05:00
Joshua Boniface 7abc697c8a Improve Zookeeper log handling 
Ensures that messages are fully read before each append. Adds more
Zookeeper hits, but ensures logs won't be overwritten by multiple
daemons.

Also don't use a set on the client side, to avoid "removing duplicate"
entries erroneously.
 2023-11-29 15:12:41 -05:00
Joshua Boniface dd6a38d5ea Properly pass the name of the exception 2023-11-16 18:05:52 -05:00
Joshua Boniface f50f170d4e Convert vmbuilder to use new Celery step structure 2023-11-16 16:08:49 -05:00
Joshua Boniface 83c4c6633d Readd RBD lock detection and clearing on startup 
This is still needed due to the nature of the locks and freeing them on
startup, and to preserve lock=fail behaviour on VM startup.

Also fixes the fencing lock flush to directly use the client library
outside of Celery. I don't like this hack but it seems prudent until we
move fencing to the workers as well.
 2023-11-10 01:33:48 -05:00
Joshua Boniface b522306f87 Increase Celery wait times 
It's a bit inefficient, but provides nicer output and a bit of settling
time between each stage.
 2023-11-09 23:54:05 -05:00
Joshua Boniface 07026efb63 Ensure OSD checks in before completing 
Avoids issues where the new OSD doesn't check in; at least the
administrator will know.

Also fixes some issues with osd_db in removal.
 2023-11-09 23:51:05 -05:00
Joshua Boniface 08411708f6 Clean up dangling references to cmd pipes 
Also removes the schema references for these CMD pipes as they are no
longer required.
 2023-11-09 23:28:14 -05:00
Joshua Boniface ce17c60a20 Port OSD on-node tasks to Celery worker system 
Adds Celery versions of the osd_add, osd_replace, osd_refresh,
osd_remove, and osd_db_vg_add functions.
 2023-11-09 23:28:08 -05:00
Joshua Boniface 89681d54b9 Port VM on-node tasks to Celery worker system 
Adds Celery versions of the flush_locks, device_attach, and
device_detach functions.
 2023-11-06 20:40:46 -05:00
Joshua Boniface a016337f57 Remove block verify in APi 
This doesn't work right and is handled by the node anyways.
 2023-11-04 02:45:10 -04:00
Joshua Boniface 7f5dd385b5 Use right key for FSID elsewhere 2023-11-03 23:51:01 -04:00
Joshua Boniface ec42b19d0e Send FSID to clients too 2023-11-03 16:37:55 -04:00
Joshua Boniface 64e37ae963 Update OSD replacement functionality 
1. Simplify this by leveraging the existing remove_osd/add_osd
functions, since its task was functionally identical to those two in
sequential order.
2. Add support for split OSDs within the command (replacing all OSDs on
the block device(s) as required).
3. Add additional configurability and flexibility around the old device,
weight, and external DB LVs.
 2023-11-03 01:45:49 -04:00
Joshua Boniface 980ea6a9e9 Adjust handling of ext_db and _count options 
Avoid the use of superfluous flag options, default them to none, and add
support for fixed-size DB LVs.
 2023-11-02 13:29:47 -04:00
Joshua Boniface 526a5f4a74 Add support for split OSD adds 
Allows creating multiple OSDs on a single (NVMe) block device,
leveraging the "ceph-volume lvm batch" command. Replaces the previous
method of creating OSDs.

Also adds a new ZK item for each OSD indicating if it is split or not.

Joshua Boniface d3b3fdfc80 Revert "Export backup images to a tar archive" 
This reverts commit 38abd078af.
 2023-10-23 11:01:16 -04:00
Joshua Boniface f1b29ea94e Initial VM restore work 2023-10-23 11:00:54 -04:00
Joshua Boniface 38abd078af Export backup images to a tar archive 
This helps ensure an easier restore as the tar archive(s) can be sent
directly to the API via the normal process of image uploading, instead
of individual disks.

Joshua Boniface 6448b31d2c Improve VM list arguments 
Use kwargs here instead of fixed args to allow default None values.
 2023-10-17 11:01:38 -04:00
Joshua Boniface b997c6f31e Add support for full VM backups 
Adds support for exporting full VM backups, including configuration,
metainfo, and RBD disk images, with incremental support.
 2023-10-17 10:15:06 -04:00
Joshua Boniface a0b45a2bcd Always create RBDs with bytes value 
Converting into human results in imprecise values when specifying bytes
directly, which in turn breaks VMDK image uploads. Instead, just use the
raw bytes value when creating the volume instead of converting it back.
