[Bug 712689] Re: Get fsfreeze in Ubuntu

[TomaszChmielewski]

Note that you shouldn't use fsfreeze on a filesystem where there is lots
of IO - notably, rootfs (/).

If you do so, all programs write-accessing it will be "frozen" as well,
which could explain your system freeze.

Try doing it on a filesystem which is not the main one, like /boot, or
similar (i.e. /var/lib/mysql, if it's a separate partition).


If "sudo fsfreeze --freeze / ; sudo fsfreeze --unfreeze /" is expected to freeze the system hard is a different question - perhaps someone should ask on a linux-fsdevel or similar mailing list.

  Please get the "fsfreeze" tool in Ubuntu. Current util-linux package

  fsfreeze is a tool to suspend access to a filesystem (Linux Ext3/4, ReiserFS, JFS, XFS) using Linux's standard API for freezing mountpoints
