From eec45643e950a5b982e1478ef57497491ec37f73 Mon Sep 17 00:00:00 2001 From: Anton Hvornum Date: Wed, 12 Oct 2022 14:17:14 +0200 Subject: Updating Partition() information after mount and unmount. (#1508) * Updating Partition() information after mount and unmount. * Cleaned up raw_parted() to gracefully output relevant partition error information. * Adding timestmap to cmd_history.txt as it's impossible to debug properly otherwise * Adding more verbose debugging information * Reinstating the lsblk retry code for PARTUUID and UUID on Partition()'s information * Added error handling for JSON parsing --- archinstall/lib/disk/blockdevice.py | 4 +++ archinstall/lib/disk/filesystem.py | 15 ++++++--- archinstall/lib/disk/partition.py | 63 ++++++++++++++++++++++++++++++------- archinstall/lib/general.py | 2 +- 4 files changed, 68 insertions(+), 16 deletions(-) (limited to 'archinstall/lib') diff --git a/archinstall/lib/disk/blockdevice.py b/archinstall/lib/disk/blockdevice.py index 736bacbc..cd0e14a6 100644 --- a/archinstall/lib/disk/blockdevice.py +++ b/archinstall/lib/disk/blockdevice.py @@ -274,12 +274,16 @@ class BlockDevice: if not uuid and not partuuid: raise ValueError(f"BlockDevice.get_partition() requires either a UUID or a PARTUUID for lookups.") + log(f"Retrieving partition PARTUUID={partuuid} or UUID={uuid}", level=logging.INFO, fg="teal") + for count in range(storage.get('DISK_RETRY_ATTEMPTS', 5)): for partition_index, partition in self.partitions.items(): try: if uuid and partition.uuid and partition.uuid.lower() == uuid.lower(): + log(f"Matched UUID={uuid} against {partition.uuid}", level=logging.INFO, fg="teal") return partition elif partuuid and partition.part_uuid and partition.part_uuid.lower() == partuuid.lower(): + log(f"Matched PARTUUID={partuuid} against {partition.part_uuid}", level=logging.INFO, fg="teal") return partition except DiskError as error: # Most likely a blockdevice that doesn't support or use UUID's diff --git a/archinstall/lib/disk/filesystem.py b/archinstall/lib/disk/filesystem.py index 5d5952a0..c8eaf0be 100644 --- a/archinstall/lib/disk/filesystem.py +++ b/archinstall/lib/disk/filesystem.py @@ -189,10 +189,13 @@ class Filesystem: return True def raw_parted(self, string: str) -> SysCommand: -
