df and lvdisplay discrepency on size.
I did an lvreduce on a logical volume followed by a lvextend on another. Everything appeared to complete successfully.
However, I ran a lvdisplay and then a df -h and the size values appear to be different between the two. The lvdisplay is showing the correct values. Why is this? How do I fix this? Thank you. |
Prior to (especially) reducing an LV, you need to resize the filesystem first. There is a document on LVM on tldp.org that explains things quite well - your distro may have similar as well.

the problem - filesystem
Syg, thanks for that link.
Unfortunately for me, while reading the LVM Administrators Guide it did not look readily apparent to me that I need to do that since I did not see the commands.....as indicated on the link you sent me: # umount /home # resize_reiserfs -s-1G /dev/myvg/homevol # lvreduce -L-1G /dev/myvg/homevol # mount -treiserfs /dev/myvg/homevol /home The book indicated: # lvreduce -L-1G /dev/myvg/homevol I'm a newbie and yes, I failed to understand this. So now, I was unable to login to the server (in St Louis) via Putty (I'm in Phoenix). The websites on that server are unavailable; some applications were in / and others in /usr. Since rebooting the server the console now says: "System Disk Error. Reboot or Enter the Root Password". I am not sure if this is enough information but I would like to hear any input as we move forward. I wish I knew of someone local in St Louis? The team that will be helping me is in India and the time differences mean will begin on Sunday morning. thanks. |
Not much any of us can do to help - too many opportunities for corruption/overlays. Hopefully you have good backups and your support team can help.
