From 1aa738691e261b3dfaf5195ec7636617a283d47a Mon Sep 17 00:00:00 2001 From: Anton Hvornum Date: Tue, 25 Jan 2022 16:09:34 +0100 Subject: Fixing the 'device_instance' being None in some partition places (#902) * Added a new return value from add_partition. Also added an exception to make sure `add_partition` can't continue silently * Added a log of debugging to add_partition * Removed a blank line (flake8) * Misconfigured variable * Added some more debugging information to partprobe * FIX: disk layout: partprobe should be called and checked only for target device (#896) * disk layout: partprobe should be called and checked only for target device * disk layout: partprobe: removed unnecessary bash subprocess * Properly defined BlockDevice() on Partition() creation. Also made sure mount-checks got some rrro handling and non-block devices should no longer attempt to return a size Co-authored-by: Anton Hvornum Co-authored-by: Victor Gavro --- archinstall/lib/disk/blockdevice.py | 2 +- archinstall/lib/disk/filesystem.py | 46 +++++++++++++++++++++++++++---------- archinstall/lib/disk/helpers.py | 20 ++++++++++++++-- archinstall/lib/disk/partition.py | 14 +++++++---- 4 files changed, 62 insertions(+), 20 deletions(-) (limited to 'archinstall/lib') diff --git a/archinstall/lib/disk/blockdevice.py b/archinstall/lib/disk/blockdevice.py index 5288f92b..5ffa06a8 100644 --- a/archinstall/lib/disk/blockdevice.py +++ b/archinstall/lib/disk/blockdevice.py @@ -241,7 +241,7 @@ class BlockDevice: count = 0 while count < 5: for partition_uuid, partition in self.partitions.items(): - if partition.uuid == uuid: + if partition.uuid.lower() == uuid.lower(): return partition else: log(f"uuid {uuid} not found.
