I recently installed ISPCONFIG and followed the perfect install. I am 99% sure I took all the default partitions for my 2TB drive but something goofed. I just ran out of space copying files due to my root partition being about 52GB and may /home being pretty much the rest. The only thing I have in the /home directory is one regular user and can be deleted if need be. Here are the stats: Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/centos-root 52403200 52403180 20 100% / devtmpfs 3996392 0 3996392 0% /dev tmpfs 4003556 0 4003556 0% /dev/shm tmpfs 4003556 197192 3806364 5% /run tmpfs 4003556 0 4003556 0% /sys/fs/cgroup /dev/mapper/centos-home 1890830276 32940 1890797336 1% /home /dev/sda1 508588 131724 376864 26% /boot Not too pretty as you can see. 100% used on my "/"! As I am not using gnome etc. and used the perfect install I will need to do this with fdisk most likely but not sure how. I spent weeks on this server and just noticed this copying huge data over when I ran out of room. OOPS! What I need to do is shrink my /home directory and give up 99% or it to "/" asap. How can I do that without loosing all the data that I already have in "/"? Thanks in advance for any replies. Please help! Art
I jumped the gun and tried a: Code: lvresize -L -200GiB /dev/centos/home -r and then got myself in trouble trying to remount the partition with superblock errors. Also, the system would not reboot so I tried: Code: xfs_repair -n /dev/centos/home and no luck. All I got was a bunch of periods with the logical drive trying to recover .....................................................................................................................................................................................................................................to find the superblocks I guess. The /dev/centos/home volume that I resized was initially 1.8TB and I simply wanted to reduce it to 200GB so I could free up the other 1.6TB for the "/" partition where I need it for my vhosts. After that I would need to resize (grow) the "/" partition to max (or 1.6GB more than it was. This obviously should have been done at install but that's the way it goes I guess when your rusty. Luckily I found some info where at least I could get back up and running by editing /etc/fstab: Code: vi /etc/fstab and commenting out the line for that logical drive "/dev/centos/home" The only file that was in the "/dev/centos/home" partition was a single user directory with nothing in it except for maybe some hidden files for the user. I need some advice before proceeding. I am running CentOS 7 and the latest version of ISPCONFIG 3. My 2 drives are RAID 1 hardware mirror array on a Dell PowerEdge 1950 so not so easy to just pull a drive to use a gui app to resize the 2 partitions. At this point I need to first figure out what the heck went wrong with reducing /dev/centos/home and get that back online before moving forward to grow my "/" partition to max with the additional 1.6GB I picked up from reducing /dev/centos/home. /etc/centos/home did reduce but I think I needed an additional command to reduce the block size too and that is why the drive would not remount or boot after I ran Code: lvresize -L -200GiB /dev/centos/home -r initially. Can't make that mistake on the "/" partition as I have way more than a single directory there and all my vhosts, mail, etc. Any help to get my home /dev/centos/home partion back online and grow the "/" partion to max via command line is welcome. Thanks, Art

I read online that xfs partitions cannot be reduced and can only be expanded. I assume that it was an xfs partition. I followed perfect install for centos7 and ISPCONFIG 3. I let the software decide partitioning. All I really had in the /home directory (/dev/centos/home) was a single directory for a regular user created during install. Now I deleted the /dev/centos/home like so: Code: lvremove /dev/centos/home and created a new 200GB home partition like so: Code: lvcreate -L 200000 -n home centos then Code: mkfs.ext3 -m 5 /dev/centos/home but even after un-commenting the line for /dev/centos/home Code: mount /dev/centos/home still won't mount. Also, I should mention that it warned me that if I created the partition I would loose the signature. I thought the volume was trash anyways so that is why I blew it away and tried to just create a new one. Still stuck on this and reluctant to try to expand my "/" partition for fear of loosing the whole system. My system is running, just without the /dev/centos/home partition and without having expanded the "/" volume another 1.4GB to 1.6GB. PLEASE HELP!!!!
To regrow the new expanded /dev/centos/root partition I also had to do a: Code: xfs_growfs -d /dev/centos/root while it was mounted. I still need help with mounting my smaller /dev/centos/home partition if anyone can help.
Thanks Srijan, No luck. I have seen lots of these pages that show how to resize and create filesystems but the problem still seems to be just getting this to auto mount in /etc/fstab. The current line in my /etc/fstab for this partition is: Code: /dev/mapper/centos-home /home xfs defaults 1 2 I have resized this partition and also it is definitely xfs via force: Code: mkfs.xfs -f /dev/centos/home I have a directory named /home when I type: Code: mount -n It is not mounting it in /etc/fstab and also will not boot without going into maintenance mode. Code: df -h does not show the partition after a: Code: mount -n I also tried prefixing the Code: /dev/mapper/centos-home /home xfs defaults 1 2 with the UUID and that didn't help either. Code: [root@ns1 ~]# mount /dev/centos/home /home [root@ns1 ~]# ls [root@ns1 ~]# df Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/centos-root 1520409600 65536816 1454872784 5% / devtmpfs 3996392 0 3996392 0% /dev tmpfs 4003556 0 4003556 0% /dev/shm tmpfs 4003556 16984 3986572 1% /run tmpfs 4003556 0 4003556 0% /sys/fs/cgroup /dev/sda1 508588 131724 376864 26% /boot /dev/mapper/centos-home 204700000 32928 204667072 1% /home At this point the xfs partition is there, it is the right size, it has an xfs filesystem on it, it will mount manually. I just need someone to show me how to get it to work again in my /etc/fstab so it will boot without going into maintenance mode. My current line does not work (with or without a UUID). Here is the current /etc/fstab line again that originally worked before I reduced the size of /home: Code: /dev/mapper/centos-home /home xfs defaults 1 2 Currently it's commented out so the system will boot. I realize that I don't really need a separate /home partion anyways and that I can do that just with a directory but I would just like to get this working again the way it was.
You can use bind mount as explained in http://www.howtoforge.com/use_mount...ctory_of_a_ispconfig_server_to_a_new_location
Hi Srijan, It looks like the article is for accessing directories and not whole xfs partitions. I tried bind as described and many variations and no luck. I edited the /etc/fstab, mount -n and then checked with "df" and the partition did not appear each time. I can manually mount this so I know the partition is good. I just can't get it too come up in fstab.
