I am moving scalix to a new server also (this weekend
)
I have just finished with rsync -av /var/opt/scalix 10.0.0.2:/var/opt but now the file size on the destination server is about 5 Gig more than on the source
Code: Select all
source: 77309068 scalix
destination: 82131976 scalix
also:
source:
88 caa
1467680 indexes
12 mobile
16 platform
17199268 postgres
28 res
57474268 s
12 sis
1167628 tomcat
44 webmail
destination:
88 caa
1467428 indexes
12 mobile
16 platform
17199304 postgres
28 res
62297388 s
12 sis
1167640 tomcat
44 webmail
Is this normal, why?
Thanks
manuel

Instead of:
rsync -av /var/opt/scalix 10.0.0.2:/var/opt
Try using:
rsync -avH /var/opt/scalix 10.0.0.2:/var/opt
The -H option preserves "hard links". Without the -H option two individual copies of the files are created. This would cause the copy to be larger than the original. Be sure to remove the /var/opt/scalix directory before trying this again.

Thanks! I'll try again (users will be down for additional 10 - 12 hours
)

OK, deleted /var/opt/scalix folder on the destination server.
Then ran rsync -avH /var/opt/scalix 10.0.0.2:/var/opt
after this did du -s * to check folder sizes, now the destination scalix folder is a few hundred meg small than the source:
Code: Select all
source | destination | folder
-------------------------------------
77320676 | 77055916 | scalix
-------------------------------------
88 88 ca
1467680 1467428 indexes
12 12 mobile
16 16 platform
17199268 17199304 postgres
28 28 res
57485876 57221328 s
12 12 sis
1167628 1167640 tomcat
44 44 webmail
I just need to make sure that I have an exact copy before I switch servers. Is it expected to have some differences like these?

Was Scalix running on the server you were copying from while you were copying? If so then yes it's quite conceivable the answer is yes.

I had shut down scalix and scalix-tomcat before starting rsync

If you are concerned then try the rsync command again. If nothing new transfers, then you are probably okay. I'm ASSUMING both servers have the same version of Scalix installed.
The next thing to do is to try it out. Look especially for issues with SAC and Webmail.

Hi, we transfered the scalix datas using rsync -av many times, without any problems, while all scalix services were should down, or a snapshot was made.

Thanks for the help
rsync -avH worked perfectly, new server is up and running.
