zfs discuss - Mar 2010 - SUMMARY: Any way to fix ZFS "sparse file bug" #6792701

Original question:

I have a Solaris x86 server running update 6 (Solaris 10 10/08
s10x_u6wos_07b X86).  I recently hit this "sparse file bug" when I
deleted a
512GB sparse file from a 1.2TB filesystem and the space was never freed up.
What I am asking is would there be any way to recover the space in the
filesystem without having to destroy and recreate it?  I am assuming before
trying anything I would need to update the server to U8.


Answer:

Installing kernel patch 141444-09 (SPARC) or 141445-09 (x86) (included in a
Live-update to Solaris 10 update 8) on my system showed the filesystem will
600GB more free space.  I did not need to export/import or upgrade the
pool...it was just available.

Thanks to all who responded to this.
