NCP™Linux Applications(including protocols like SAMBA)


Novell Storage Services™ and LUM

• Novell® Storage Services uses eDirectory™ GUIDs internally

• Linux passes UIDs to Novell Storage Services

• LUM enabled users link the eDirectory user to a Linux UID

• Novell Storage Services maintains multiple ID caches

– G2I, I2G and SEV Caches


NCP™ Server – Novell Storage Services™

NCP Client eDirectory™

NCP Server


1) User and Groupinformation forthe connectionJoe is using

2) Create file foo.txtlogged in as Joe

3) Apply trusteerights-basedon path andconnection

4) Create foo.txt as root

5) Change ownerto Joe (by GUID)


Novell Storage Services™ and NCP™

• NCP has its own trustee store– Synced with Novell® Storage Services trustees at run time.

– Ability to re-sync on demand

• NCP does not require LUM enablement• NCP runs in user space (ndsd addr space) as root and

uses various methods to communicate with nss– Normal VFS layer calls (i.e. open, close, read, write)– Extended attributes and zAPIs for special operations– _admin commands for special operations– NEB events generated by Novell Storage Services– Ncp2nss daemon facilitates this communication

•


Novell Storage Services™ and NCP™

• OES1 considerations– Owner, modifier, archiver and deleter are all root– User quotas will not work

• OES2 considerations– Owner will be correct, and user quotas will work– Modifier, archiver, and deleter will still be root

• NCP implements LONG name space• NCP maintains the UIDMapping cache to speed up G2I

lookups



eDirectory™Client LUM

VFS – Novell Storage Services™

1) Create file foo.txt logged in as Joe— request comes to Novell Sorage Services as UID 705

2) Novell Storage Services requests the eDirectory name for UID 705—LUM returns joe.acme

3) Novell Storage Services requests security equivalence information for UID for joe.acme and eDirectory return a list of equivalent users and group memberships

4) Novell Storage Services does normal trustee checking based on the users and groups returned by eDirectory


VFS Applications

• Novell Storage Services™ is registered as a Linux file system

• Protocols– Access protocols, NCP™,and Novell® CIFS use both the VFS layer and

special interfaces

– AFP uses zAPI interface

– Other protocols use the VFS layer

• Other Applications– Must have LUM enabled users

• Trustee rights are enforced– Does not use the group ID

• All Novell Storage Services capabilities are available


• The POSIX read/write/execute attributes represent NetWare® attributes:

– Read: NetWare hidden attribute

– Write: Set unless it is a read-only file

– Execute: NetWare execute attribute (cannot copy) / or subdirectory

VFS Applications

Novell Storage Services™

Recent Changes, Tuning and Troubleshooting


Improved NCP™/NSS Integration to Support Salvage for Non-LUM users• NSS and NCP enhanced to retain deleter information

for files deleted by non-LUM users

• With latest OES2SP1 patches (or) OES2 SP2

– Owner, modifier and deleter will be correct

– User quotas and salvage will work

• Both LUM and non-LUM scenarios are nearly the same

– Users NO longer need to be LUM enabled


Improved NCP/NSS Integration for LONG name space• NCP™ implements LONG name space• NCP access optimized if NSS volumes are mounted

with LONG name space – with latest patches for OES2SP2/SP1

• Significant improvement in performance/scalability

• Reduction of load/utilization on NCP/ndsd/ndp• LONG as default NSS mount name space since SP1

– Novell® GroupWise® had issues with LONG name space, but those issues are fixed with recent hot fixes from GroupWise


Novell Storage Services™ ID Cacheon Novell® Open Enterprise Server 2 Linux

• NCP™ supports non-LUM map entries with its cache– With latest patches for SP1/SP2

• NSS ID Cache Tuning Paremeters– Reset various ID caches

> nss /ResetIDCache

– Modify the reset intervals of ID caches> nss /IDCacheResetInterval=value> Default – 25 hours

– Modify the size of ID caches (Latest patches for SP1/SP2)> nss /IDCacheSize=value> Default - 16K

– Monitor ID cache statistics (OES2SP3)


NCP™ Dir Cache Tuningon Novell® Open Enterprise Server 2 Linux

• Monitor usage and evictions – LOG_CACHE_STATISTICS

• Configure based on working set and available memory– MAXIMUM_CACHED_FILES_PER_VOLUME

> Default - 20000– MAXIMUM_CACHED_SUBDIRECTORIES_PER_VOLUME

> Default - 50000– MAXIMUM_CACHED_FILES_PER_SUBDIRECTORY

> Default - 2048– Cache Entry memory usage - ~216 bytes + Full path name

• Additional Information> http://www.novell.com/documentation/oes2/file_ncp_lx/data/bc06ts8.html> TID 7004888 – NCP Performance Tuning on OES2 Linux

http://www.novell.com/documentation/oes2/file_ncp_lx/data/bc06ts8.html


Novell Storage Services™ IO SystemImprovements on Novell® Open Enterprise Server 2 Linux

• OES2 SP2– Improved Read-Ahead Algorithm (Stepping Window)

• OES2 SP3– Improved IO Scheduler Interactions – Multi-Page BIO Support

• Recommended Configuration– With latest patches for OES2 SP2/SP1

> nss /noUnplugAlways

– XEN Guest> Change the default noop IO scheduler to cfq

– Modify Read Ahead Blocks based on access pattern> Default readAheadBlks count for NetWare®/OES1 was 2


Novell Storage Services™ Caching

• Files– Objects in memory (Beasts / Inodes)

– Packed on disk in 4K Blocks (Metadata Blocks)

• Metadata– 4K Pages in Memory

– Unpacked into Objects

• User Data– 4K Pages in Memory

– Saved on disk as 4K Blocks (User data Blocks)


File Caching

• Novell Storage Services™ on NetWare®

– nss /ClosedFileCacheSize> Maximum Number of “notInUse” Files in memory> Based on the available memory in the system> NSS does its own balancing

• Novell Storage Services on Linux– nss /ClosedFileCacheSize– Linux Memory Pressure

> Inodes in memory> /proc/slabinfo

» lsa_inode_cache

> Linux will influence the total number of Files in memory


Linux Page Cache

• Linux memory (Novell Storage Services™ is akernel module)

– Kernel Memory > Low Memory – directly addressable by the kernel

– User Memory > High Memory – Kernel has to map it before using

• 32-bit v/s 64-bit– 32-bit OES Linux Servers

> 1 Gig of Low Memory (by default)> Custom Linux Kernels can increase the default

– 64-bit OES Linux Servers> All memory is Low Memory


Novell Storage Services™ Page Cacheon Novell® Open Enterprise Server 2 Linux

• OES2 Linux– 64-bit Servers

> Not Low Memory Constrained, so HiMem Cache not needed

> nss /MinBufferCacheSize to configure Metadata Cache

> User Data integrated into Linux Cache

– 32-bit Servers> Use HiMem to cache Novell Storage Services metadata

> nss /HighMemoryCacheType=cachetype (private, linux, OR none)

> Default is private

> Similar to OES1 Linux SP2 with the latest patch

> User Data integrated into Linux Cache


Novell Storage Services™ Memory on Novell® Open Enterprise Server 2 Linux

• OES2SP3

– Ability to look at comprehensive memory usage

– Ability to look at memory consumed for different data structures

– Ability to tune the configurations

– Should help troubleshoot memory build-up issues


Novell Storage Services™/NCP™ Issueson Novell® Open Enterprise Server 2 Linux

• Resource Migration Hangs

– Check Unload.out file

– Stack dump of user space processes (gstack)

> adminusd, ndsd, ncp2nss

– Stack dump of kernel threads

> echo 1 > /proc/sys/kernel/sysrq

> echo t > /proc/sysrq-trigger

– Core (user-space processes and kernel) if necessary



• Slow File Access

– Apply ALL the SP1/SP2 Patches

> Optimized for NSS volumes mounted in LONG name space

> Optimized for both LUM and non-LUM users access

> Reduced memory usage

– Tune NCP Dir Cache

– Tune NSS ID Cache

– Process of elimination (NCP, NSS, ...)



• Random Reboots/Multiple Poison Pills– Apply ALL latest patches

– Ensure there are NO corruptions or double activations> Verify

> MSAP Steal

– Determine poison pill is an after effect of the reboot or it caused the reboot

> Setup kdump to capture core

> Setup sysrq to capture core if hung


nsscon

• NetWare® like console

– nss /help

– nss /find

– nss options for tuning, configuration

– Can be set persistently in /opt/novell/nss/conf/nssstart.cfg


Ravsui

• Pool in maintenance state– nsscon

> nss /poolMaintenance=<POOLNAME>

• ravsui verify <POOLNAME>– Verify a pool– ravview vbfn <POOLNAME>

> Will show the results from verify

• ravsui rebuild <POOLNAME>– Rebuild a pool– ravview rtfn <POOLNAME>

> Will show the results from rebuild


Novell Storage Services™ Future Work

• Support for >8TB Pools– Requires media change, NOT backwards compatible– Challenges

> Co-existence of old and new media formats> Migration of data from old to new media formats

• Support for >2TB Partitions• SLES11 support• NO release vehicle determined yet
