Please see attached file displaying current partitions on the ES47 server.
I am running out of disk space on /mdxrpd and /mdxrpl partitions so I need to reorganise these two partitions.
My question is how can I splie the /mdxrpd and /mdxrpl partions out of the data_domain1 and put these two partitions in separate file domains without losing any data on these two partitions?
You can see the data_domain1 consists of 6 partions within this file domain.
Any help would really appreciated.
Solved! Go to Solution.

Re: How to split a partition in the same file domain
Filesets are very flexible, just names realy. The storage behind it is shared by all filesets inthe domain as you can see from the 'available' column.
Here is what you do.. untested.. check spelling of comands
bring down application
mkfset data_domain2 mdxrpd
mkdir /mdxrpd_old
umount /mdxrpd
mount data_domain1#mdxrpd /mdxrpd_old
mount data_domain2#mdxrpd /mdxrpd
cd /mdxrpd_old
vdump 0f - / | (cd /mdxrpd; vrestore -xf -)
bring up application
change mdxrpd entry in /etc/fstab
wait hours or days to make sure all is well
umount /mdxrpd_old
rmfset data_domain1 mdxrpd
presto, 74M blocks more available on domain1 ready to be used by mdxrpl
hth,
Hein.

SolutionFirstly, may I correct your terminology. They're not partitions they're filesets.
The simple solution is to simply create new filesets in data_domain2 for mdxrpd and mdxrpl and then use vdump and vrestore to copy the data between them.
You'll need to ensure that nothing is changing on these two mount points in order to do this, so shutdown any applications etc.
So...
mkfset data_domain2 mdxrpd
mkfset data_domain2 mdxrpl
mkdir /copy_mdxrpd
mkdir /copy_mdxrpl
mount -t advfs data_domain2#mdxrpd /copy_mdxrpd
mount -t advfs data_domain2#mdxrpl /copy_mdxrpl
vdump -0f - /mdxrpd | vrestore -xf - -D /copy_mdxrpd
vdump -0f - /mdxrpl | vrestore -xf - -D /copy_mdxrpl
umount /copy_mdxrpd
umount /copy_mdxrpl
Modify /etc/fstab and change data_domain1 to data_domain2 for /mdxrpd and /mdxrpl
umount /mdxrpd
umount /mdxrpl
mount /mdxrpd
mount /mdxrpl
Check everything has copied correctly, then remove the old filesets from data_domain1
rmfset data_domain1 mdxrpd
rmfset data_domain1 mdxrpl
Hope this helps,
Regards,
Rob
