%description
GFS (Global File System) is a cluster file system. It allows a cluster
of computers to simultaneously use a block device that is shared
between them (with FC, iSCSI, NBD, etc...). GFS reads and writes to
the block device like a local filesystem, but also uses a lock module
to allow the computers coordinate their I/O so filesystem consistency
is maintained. One of the nifty features of GFS is perfect consistency
- changes made to the filesystem on one machine show up immediately on
all other machines in the cluster.

%description -l pl.UTF-8
GFS (Global File System) to klastrowy system plików. Pozwala klastrowi
komputerów na jednoczesne korzystanie z urządzenia blokowego
dzielonego między nimi (poprzez FC, iSCSI, NBD itp.). GFS odczytuje i
zapisuje urządzenie blokowe jak lokalny system plików, ale używa
dodatkowo modułu blokującego, aby umożliwić komputerom koordynowanie
ich operacji I/O w celu zachowania spójności systemu plików. Jedną z
szykownych możliwości GFS-a jest idealna spójność - zmiany wykonane w
systemie plików na jednej maszynie natychmiast pokazują się na
wszystkich innych maszynach w klastrze.
