Hello,
has someone successfully restored a filesystem with more than 3 mio files ?
Currently our 'restore' is now running 20 hours and it still shows
ANS1899I ***** Examined 2,689,000 files *****
ANS1899I ***** Examined 2,690,000 files *****
ANS1899I ***** Examined 2,691,000 files *****
...
Because there are about 3.5 mio files to be restored it may run for a
very long time. At this stage there is no byte 'restored' yet --- just
doing this 'Examination'.
The dsmc on the solaris(10) client-system ( v440, 4 cpus, 16GB mem ) is showing
CPU PID User NI State Size RSS CPU% SCPU% CPU-Time Command
4T 8970 root 0 on 1011m 1009m 100.4 0.0 12:30:48 dsmc
... there is nothing else running there.
I seems that the 'restore' slows down with the number of files 'examined'
We have both tried V5.3.0.0 solaris- client and this current session
has client Version 5.1.6.5 .
The process is excessively doing string-operation like 'strcmp' and 'strlen'.
The restore - command is:
dsmc restore -quiet -virtualnode=mail /mail/ /data2/mail/
The /data2 -fs is empty and our dsm.sys/dsm.opt looks like:
blackhole:...//# cat /opt/tivoli/tsm/client/ba/bin/dsm.opt
subdir yes
testflag disablenqr
blackhole:...//# cat /opt/tivoli/tsm/client/ba/bin/dsm.sys
servername adsmaix
commmethod tcpip
tcpport 1500
tcpserveraddress xxxxxxx

errorlogname /var/adm/dsmerror.log
schedlogretention 7
errorlogretention 14
inclexcl /opt/tivoli/tsm/client/ba/bin/exclude.lis
tcpnodelay yes
blackhole:...//#
The 'testflag disablenqr' we used because at least for a smaller number of
files ( eG 10000 files ) it had a tremendeous performance effect.
The server is showing often SendWait - currently up to 20 s WaitTime:
