Re: possible regression

[Curtis Gedak]

To my knowledge, the problem of "failed to inform kernel of partition 
changes" continues with parted-2.2.

Based on reports from users of GParted, the problem first appeared after 
parted-1.8.8 with some development snapshots from git (e.g., 
parted-1.8.8 + development code in git) and parted-1.9.0.

Several attempts have been made to address this problem, but none appear 
to have been able to eradicate this bug.  I believe that most recent 
attempt to resolve this problem is the following parted git commit:
  libparted: avoid race in informing the kernel of partition table changes
http://git.debian.org/?p=parted/parted.git;a=commit;h=0f850220b3f26bb969a1a7ff78dc550691a89566

This above commit is included in the parted-2.3 release.

Would you be able to test again using parted-2.3?


Unfortunately the problem does not reliably occur on all computer 
systems, which has made this bug very elusive.

Reports from users of GParted regarding file system resize problems that 
occurred when this problem happened can be seen in the in the following 
GParted forum post:
