Hi everyone,
I need to resize an online drbd resource. Drbd is on top of LVM.
resource drbd0 {
on node1.aka.edu.au {
device /dev/drbd0;
disk /dev/lvmc1/export1;
address 192.168.1.1:7789;
meta-disk /dev/sdd1[0];
}
on node2.aka.edu.au {
device /dev/drbd0;
disk /dev/lvmc1/export1;
address 192.168.1.2:7789;
meta-disk /dev/sdd1[0];
}
Could someone who done this before confirm my steps below:
1. Add more space to Logical Group lvmc1 on node1 and node2
2. Extend logical volume /dev/lvmc1/export1 on node1 and node2 ( growing
from 1 TB to 1.5 TB )
3. Grow ext3 file systems using either
ext2online /dev/lvmc1/export1 or
reseizefs /dev/lvmc1/export1
4. drbdadm resize /|resource|/ ( in my case drbd0 ) on the primary node.
5. repeat for 1 - 4 for other resources.
Questions:
a. It is irrelevant on which node ( primary or secondary ) steps 1 & 2
are carried out first. Can you confirm this, pls?
b. Can you confirm that steps 3 and 4 are in correct order?
c. Can you confirm that both steps 3 and 4 can be done online?
d. Will step 4 cause any performance degradation? (How should it take?)
Thank you in advance.
