Hello, many linux SW is starting to implement new lzma compresson instrad of old zlib (gzip) od bzip2. lzma is default comrpession in very good compression SW 7-zip, which is faster and have higher compression ratio then bzip2 or rar. Currently its probalby the best compressor in therms of compression and decompression speed / compression ratio. In linux there...

...ystem, that has own implementation of ACL (NFS v4 ACL). Samba uses zfsacl and acl_xattr modules for converting NT ACL to ZFS ACL and extended attributes of file in this OS. ZfsOnLinux team ported ZFS as a number of kernel-linked modules to Linux OS, so ZFS on Linux supports NFS ACL, deduplication, compresson and other features of Solaris ZFS v.28. But NFS ACL is not compatible with POSIX ACL, the one type of ACL Samba can use on Linux platform. Acl_xattr and acl_tdb modules cannot solve problem, because it's required a filesytem with POSIX ACL support for storing generic ACL attrbutes. So, can I b...

I''m observing the following behavior in our environment (Sol10U2, E2900, 24x96, 2x2Gbps, ...) - I''ve a compressed ZFS filesystem where I''m creating a large tar file. I notice that the tar process is running fine (accumulating CPU, truss shows writes, ...) but for whatever reason the timestamp on the file doesn''t change nor does the file size change. The same is
