Tony Asleson	feaf46863b	lvmdbusd: Use common func. for checking missing LV keys	2022-09-16 10:49:37 -05:00
Tony Asleson	d42bdb07de	lvmdbusd: Re-work error handling ... Introduce an exception which is used for known existing issues with lvm. This is used to distinguish between errors between lvm itself and lvmdbusd. In the case of lvm bugs, when we simply retry the operation we will log very little. Otherwise, we will dump a full traceback for investigation when we do the retry.	2022-09-16 10:49:37 -05:00
Tony Asleson	1839702cb4	lvmdbusd: Remove use of tmp variables ... We can use tuple expansion from the command handler functions directly.	2019-10-30 10:38:40 -05:00
Tony Asleson	df38eb49ab	lvmdbusd: Remove duplicate error handling code ... vg, lv, pv code had the same function for handling command execution. Move to utility function and abstract the difference.	2019-10-30 10:38:40 -05:00
Tony Asleson	7a6e438df8	lvmdbusd: Ensure vg_uuid is present ... In some cases we are seeing where there are no VGs, but the data returned from lvm shows that the PVs have the following for the VG: "vg_name":"[unknown]", "vg_uuid":"" The code was only checking for the exitence of the VG name and we called into the function get_object_path_by_uuid_lvm_id which requires both the VG name and the LV name to exist (asserts this) which results in the following stack trace: Traceback (most recent call last): File "/home/tasleson/lvm2/daemons/lvmdbusd/utils.py", line 563, in runner obj._run() File "/home/tasleson/lvm2/daemons/lvmdbusd/utils.py", line 584, in _run self.rc = self.f(*self.args) File "/home/tasleson/lvm2/daemons/lvmdbusd/fetch.py", line 26, in _main_thread_load cache_refresh=False)[1] File "/home/tasleson/lvm2/daemons/lvmdbusd/pv.py", line 48, in load_pvs emit_signal, cache_refresh) File "/home/tasleson/lvm2/daemons/lvmdbusd/loader.py", line 37, in common objects = retrieve(search_keys, cache_refresh=False) File "/home/tasleson/lvm2/daemons/lvmdbusd/pv.py", line 40, in pvs_state_retrieve p["pv_attr"], p["pv_tags"], p["vg_name"], p["vg_uuid"])) File "/home/tasleson/lvm2/daemons/lvmdbusd/pv.py", line 84, in __init__ vg_uuid, vg_name, vg_obj_path_generate) File "/home/tasleson/lvm2/daemons/lvmdbusd/objectmanager.py", line 318, in get_object_path_by_uuid_lvm_id assert uuid AssertionError	2017-09-21 14:35:36 -05:00
Tony Asleson	681d69c70a	lvmdbusd: pv.py, remove duplicate code ... Move similar code to common functions, less is more!	2017-02-01 16:51:00 -06:00
Tony Asleson	dcdef9647b	lvmdbusd: Add cfg.load to pv remove ... The global dbus state does not match lvm with simply removing the pv dbus object.	2016-11-17 11:35:16 -06:00
Tony Asleson	60de09b00c	lvmdbusd: Don't use dbus lib in worker thread ... Simplify the code paths so that we don't utilize the dbus library code when we are in worker thread context. ref. https://bugs.freedesktop.org/show_bug.cgi?id=98521	2016-11-02 16:39:03 -05:00
Tony Asleson	9241dbdf57	lvmdbusd: Correct return type for empty PeSegments	2016-08-29 15:26:56 -05:00
Tony Asleson	2bb09b4015	lvmdbusd: Be more explicit on return values ... The python dbus library tries to make best on what the dbus type is based on python data type. Some times it gets this wrong, so we will be explicit.	2016-08-29 15:26:55 -05:00
Tony Asleson	b717e8fe1d	lvmdbusd: Rename get_object_path_by_lvm_id ... Renaming to get_object_path_by_uuid_lvm_id, to clarify that both the uuid and the lvm id are required.	2016-06-10 15:28:42 -05:00
Alasdair G Kergon	5987562cf9	lvmdbus: Add new daemon.	2016-02-17 23:53:35 +00:00
