Subject: [PATCH] libext2fs: don't ignore fsync errors
|
|
Git-commit: 025d31b17a67953ce96741588bd911e6e66b6e03
|
|
References: bsc#1038194
|

|
|
Today, if mke2fs experiences IO errors (say, on a thin device
|
|
which filled up during mkfs), mke2fs is silent and returns
|
|
success even though the filesystem was not properly created.
|
|
|
|
Catch errors from the io_channel_flush() callchain to
|
|
fix this up. Fix formatting of the printed error as
|
|
well:
|
|
|
|
...
|
|
Creating journal (262144 blocks): done
|
|
Writing superblocks and filesystem accounting information:
|
|
Warning, had trouble writing out superblocks.
