Title:
[21.04 regression] formatting vfat times out
Status in udisks2 package in Ubuntu:
Fix Released
Status in udisks2 source package in Hirsute:
Fix Committed
Bug description:
* Impact
Formatting devices to vfat fails in some cases due to an
incompatibility with the new dosfstools version
* Test case
see comment #5
or
- $ sudo modprobe scsi_debug
- check what device is assigned
- $ sudo busctl call org.freedesktop.UDisks2
/org/freedesktop/UDisks2/block_devices/DEVNAME org.freedesktop.UDisks2.Block
Format 'sa{sv}' vfat 0
(replace DEVNAME by the actual device name, 'sdc' for example)
the formatting should work which you can verify by
- $ blkid -p /dev/DEVNAME
* Regression potential
The changes is specific to vfat handling so that's the feature to
focus on while testing, make sure than creating, deleting, renaming
vfat partitions from gnome-disks is working.
[racb] An upstream "precautionary" partprobe is being added following
the mkfs for vfat, when it didn't do this before. This is a change in
behaviour that might expose a problem elsewhere.
----------------------------
There is a regression somewhere between udisks, udev, and dosfstools.
Formatting a device with vfat hangs and fails:
# blkid -p /dev/sda
(nothing)
# busctl call org.freedesktop.UDisks2
/org/freedesktop/UDisks2/block_devices/sda org.freedesktop.UDisks2.Block Format
'sa{sv}' vfat 0
(long pause)
Call failed: Error synchronizing after formatting with type `vfat': Timed out
waiting for object
# blkid -p /dev/sda
/dev/sda: PTUUID="3690494f" PTTYPE="dos"
OTOH, formatting as ext4 works fine:
# wipefs -a /dev/sda; wipefs -a /dev/sda
# busctl call org.freedesktop.UDisks2
/org/freedesktop/UDisks2/block_devices/sda org.freedesktop.UDisks2.Block Format
'sa{sv}' ext4 0
(immediately succeeds)
# blkid -p /dev/sda
/dev/sda: UUID="8bea7475-6af5-4835-86d0-0e5b2cb5500e" VERSION="1.0"
BLOCK_SIZE="4096" TYPE="ext4" USAGE="filesystem"
I tested this to a QEMU emulated disk, but it reproduces equally well
against a `modprobe scsi_debug` device.
