dva puta sam pokušavao sa vzmigrate --online ...

ali stvar se čudno ponaša, prenese cca 12.5 GB pa se onda vrati na cca 3.5 GB (stanje podataka na odredišnom serveru) i tako zaglavi ... to je neki problem očigledno sa rsync-om

idem sada na offline migraciju a prema http://wiki.openvz.org/Checkpointing_and_live_migration

suspendujem sesiju

root@dualco-705:~# vzctl chkpnt 701 --suspend

Setting up checkpoint...
        suspend...
        get context...
Checkpointing completed succesfully

dampujem je

root@dualco-705:~# vzctl chkpnt 701 --dump --dumpfile /backup/701.dump

Setting up checkpoint...
        join context..
        dump...

a sada na hp-smraka-1

root@hp-smraka-1:~# scp root@dualco-705.bring.out.ba:/backup/*dump .
root@dualco-705.bring.out.ba's password: 
701.dump                                       23%  178MB  11.2MB/s   00:52 ETAroot@hp-smraka-1:~# 

root@hp-smraka-1:/etc/vz/conf# vzctl restore 701 --undump --dumpfile ~/701.dump 
Restoring VE ...

        undump...
Error: undump failedVE start failed

ali sam ja prolupao - ovo ne može da se radi na drugoj mašini

nego treba da se sada kada smo suspendovali mašinu izvršiti migraciju

root@dualco-705:~# vzmigrate -v  192.168.45.90 701

isto kao i kod online migracije - čudno do boli

root@hp-smraka-1:~# du -s  /vz/private/701
12450064        /vz/private/701
root@hp-smraka-1:~# du -s  /vz/private/701
3751384 /vz/private/701
root@hp-smraka-1:~# du -s  /vz/private/701
3751384 /vz/private/701

root@dualco-705:/vz/private/701/opt/zimbra# du -s -h store db log logger dspam-3.6.2/var/dspam/data

2,5G    store
521M    db
2,2G    dspam-3.6.2/var/dspam/data
12G     log
201M    logger

imamo luđački veliki log

-rw-r--r-- 1 hernad lpadmin   12G 2008-02-17 16:25 zmmtaconfig.log
-rw-rw-rw- 1 hernad lpadmin     5 2008-02-17 10:58 zmmtaconfig.pid
-rw-r--r-- 1 root   root        6 2008-02-17 10:59 zmtomcatmgr.pid

prebacujem ga na

root@dualco-705:/vz/private/701/opt/zimbra/log# mv zmmtaconfig.log /backup

sada offline migracija uspjeva !

idem na novi server hp-smraka-1

zimbra@zimbra-1:/$ zmcontrol status
Host zimbra-1.sigma-com.net
        antispam                Running
        antivirus               Stopped
                zmclamdctl is not running
        imapproxy               Running
        ldap                    Running
        logger                  Running
        mailbox                 Running
        mta                     Running
        snmp                    Running
        spell                   Running

nakon 4-5 minuta antivirus je ok

zimbra@zimbra-1:/$ zmcontrol status

        mta                     Running
        snmp                    Running
        spell                   Running

zadovoljnan sam kako se ponaša server s obzirom da na hp-smraka-1 ima samo 1.5 GB RAM-a - ne vidim usporenje, dapače

pravim backup na smraki,

tar cvfz 701.tar.gz ...

i najduže traje backupiranje dspam (var/data ...) direktorija

čovječe ovo 100 godina traje ovo arhiviranje dspam dir-a
