From 67bb00c655cbe85e740a9d7e8b233dd4d69a79e2 Mon Sep 17 00:00:00 2001 From: Anton Hvornum Date: Sat, 3 Apr 2021 14:59:40 +0200 Subject: This partially addresses #151. Which might require more than just the path being returned. As the blkid might not be correctly identifying it in the bootloader step. But we'll have to test and see. --- archinstall/lib/disk.py | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'archinstall/lib/disk.py') diff --git a/archinstall/lib/disk.py b/archinstall/lib/disk.py index 9ad49ac2..95418ab1 100644 --- a/archinstall/lib/disk.py +++ b/archinstall/lib/disk.py @@ -78,10 +78,15 @@ class BlockDevice(): return drive['back-file'] elif self.info['type'] == 'disk': return self.path + elif self.info['type'][:4] == 'raid': + # This should catch /dev/md## raid devices + return self.path elif self.info['type'] == 'crypt': if 'pkname' not in self.info: raise DiskError(f'A crypt device ({self.path}) without a parent kernel device name.') return f"/dev/{self.info['pkname']}" + else: + raise DiskError(f"Could not locate actual block device path for {self.path}") # if not stat.S_ISBLK(os.stat(full_path).st_mode): # raise DiskError(f'Selected disk "{full_path}" is not a block device.') -- cgit v1.2.3-70-g09d2 From 1c3287bc813d0652bc671c120c52b99a368e31fe Mon Sep 17 00:00:00 2001 From: Anton Hvornum Date: Sat, 3 Apr 2021 15:11:10 +0200 Subject: Removed a breaking change while fixing hardware raids --- archinstall/lib/disk.py | 2 -- 1 file changed, 2 deletions(-) (limited to 'archinstall/lib/disk.py') diff --git a/archinstall/lib/disk.py b/archinstall/lib/disk.py index 95418ab1..371bf7f5 100644 --- a/archinstall/lib/disk.py +++ b/archinstall/lib/disk.py @@ -85,8 +85,6 @@ class BlockDevice(): if 'pkname' not in self.info: raise DiskError(f'A crypt device ({self.path}) without a parent kernel device name.') return f"/dev/{self.info['pkname']}" - else: - raise DiskError(f"Could not locate actual block device path for {self.path}") # if not stat.S_ISBLK(os.stat(full_path).st_mode): # raise DiskError(f'Selected disk "{full_path}" is not a block device.') -- cgit v1.2.3-70-g09d2 From 7333fe109ce832dcda1daa7f363e352990e66886 Mon Sep 17 00:00:00 2001 From: Anton Hvornum Date: Sat, 3 Apr 2021 15:18:35 +0200 Subject: Converted the raise exception into a log.

When a newly /boot partition is created with no content or incorrect filesystem (meaning, no file system yet), the .has_content() call will crash due to incorrect fstype. Which means we should be able to skip the check and assume it's safe to format. Because there's no way (?) other OS:es can store something on the boot partition on a broken FS. --- archinstall/lib/disk.py | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) (limited to 'archinstall/lib/disk.py') diff --git a/archinstall/lib/disk.py b/archinstall/lib/disk.py index 52c6e287..44d46c8b 100644 --- a/archinstall/lib/disk.py +++ b/archinstall/lib/disk.py @@ -245,9 +245,15 @@ class Partition(): if self.allow_formatting is False: log(f"Partition {self} is not marked for formatting.", level=LOG_LEVELS.Debug) return False - elif self.target_mountpoint == '/boot' and self.has_content(): - log(f"Partition {self} is a boot partition and has content inside.", level=LOG_LEVELS.Debug) - return False + elif self.target_mountpoint == '/boot': + try: + if self.has_content(): + log(f"Partition {self} is a boot partition and has content inside.", level=LOG_LEVELS.Debug) + return False + except SysCallError as err: + log(err.message, LOG_LEVELS.Debug) + log(f"Partition {self} was identified as /boot but we could not mount to check for content, continuing!", level=LOG_LEVELS.Debug) + pass return True -- cgit v1.2.3-70-g09d2 From b2927a50670d92bb99e0b8a23e6321e4a8c6f26b Mon Sep 17 00:00:00 2001 From: Anton Hvornum Date: Sat, 3 Apr 2021 16:22:09 +0200 Subject: This should fix #151, by using lsblk instead of /dev/disk/by-partuuid.
