2.6TB filesystem to be copied or moved to another FS ?
Hi folks,
I have a filesystem which is 2.6TB big and would like to copy/mirror this filesystem on another volume group.
1) What is the fastest way to copy or mirror it to another filesystem without shutting down production vg ( oracle is using the filesystem )
2) Is there any way to estimate how long it will take to copy/mirror the filesystem if it is required to shutdown Oracle ?
/u03 is the filesystem which has to be copied/moved to another new filesystem
two options which i thought of:
(1) to mirrorvg ie., mirror oraclevg to the new vg but this process will be very slow if ORACLE is running is continuously accessing the filesystem /u03 while mirror process is under way.
(2) shutdown oracle, use copy filesystem command and move it, but need to know how long will it take to move 2.6TB since Oracle cannot be down for more than 10 hours

I did little research on the internet and found few documents which showed the recommended procedure
1) either by backup and restore ( which will preserve the file permissions and inode information )
2) cplv
now regarding cplv, no document points out the following and i hope some knows the answer here on the forum
1) can it be used to copy 2.6 TB ? since it is very big filesystem ?
2) will it preserve file permissions and inode information ?
3) what is the transfer/copy speed ? this is important to know since cplv can be only done when the filesystem is unmounted ( not in use ) so 2.6TB takes like 2 days then have to go with another solution like backup and restore.

Hi guys!
Could you tell me what's the difference of filesystem of Solaris to filesystem of Windows? I need to compare both.
I have read some over the net but it's so much technical. Could you explain it in a more simpler term? I am new to Solaris. Hope you help me guys.
