SambaXP 2008 Conference - Day 1
- Schlomo Schapiro - The Simple High Available Linux File Server
- Real hardware as primary server, "virtual cold stand-by server"
- Local storage and SAN
- GPT for Partitions bigger than 2TB
- Nice implementation of cold stand-by cluser
- Oliver Tennert - Parallel NFS
- HPC: More and more data
- More nodes, more nodes, more throuput
- Not a good solution: Cluster NFS
- Distributed File Systems: IBM's GPFS, SGI's CXFS, PanFS, PVFS2, ...
- NFSv4 includes everything a network file system needs (NFSv3 does NOT)
- pNFS optional part of NFS 4.1
- Separtion of metadata path/server and data path/server
- SAP (Storage Access Protocoll) not specified, incompatible clients get data from metadata server
- Current state: "should work", many layouts on the way
- Steve French: From DFS to Kerberos: Update on Linux CIFS client
- Kerberos support on way into the kernel
- Apple symlinks over CIFS are the 4th way to do it
- Setting up all stuff needed and/or supported by NFSv4 is a pain in ...
- Jelmer Vernooij, Andrew Bartlett: Samba 4, where are we now?
- Samba 4 Alpha 3 released 2 weeks ago, announcement mail gets eaten...
- More than TechPreview, basic features completed, useable for SOME environments, needs more testers
- No more EJS, Python rulZ! ;-) And GNU Make
- Much work done in LDB subsystem/internal database: Subtree rename, sort of grouo policy, (some) schema validation
- Autoconfiguration of backend (OpenLDAP)
- SWAT disabled due to JS->Python, SoC project
- MMC works and some group policy
- Beta at end of THIS year! AD DC, file search, AD Member
- What would stop YOU using Samba 4?
- Andrew Bartlett: The little shop of horrors: AD's notation of LDAP
- AD "based on" LDAP, an IETF standard protocol to access a standard X.509 directory
- AD's schema is different: AD CN is not LDAP CN (multi values), AD top hast 75 new elements, ...
- No DNS and NTP in Samba 4 but ideas how it could/should work
- Volker Lendecke: Samba 3.2 Infrastructure changes
- Un-/Marshalling code moved to PIDL
- One overall cache for nearly everything
- 3.2 is slower than 3.0 (much more malloc())
- Solution: remove malloc() calls, use talloc_*() instead
- Jelmer Vernooij: RPC scripting using Python
- Samba 3.0 had already Python bindings
- Switch now to stop people from coding EJS (may be removed later)
- More potential developer with Python
- PIDL generates Python bindings
- Python/SoC: smbclient, SWAT, Samba-GTK
- At the moment use "smbpython"
- python-ldb/python-tdb already in Debian/Ubuntu
- Jelmer: "Next version of Perl has unicode operators..."
- Tridge: "I have a purpose in life! Telling people how to resize fonts in xterms!"
