Please check out [this] blogpost with an updated procedure for resizing disks.
This week I wanted to update my vRealize deployment with vRA 8.4.1 and VIDM 3.3.5. My starting environment is vRSLCM 8.4, VIDM 3.3.4 and vRA 8.4.
The first step, is to upgrade vRSLCM. If you try to add VIDM 3.3.5 or vRA 8.4.1 to vRSLCM 8.4 the error “Selected files checksums does not match with any product versions supported by vRealize Lifecycle Manager” is shown.
Depending on your environment, you can use an online repository or do this manually by downloading the update file “VMware-vLCM-Appliance-126.96.36.199-18067607-updaterepo.iso”
After that, mount the iso on the VM, go to Home, Settings, System Upgrade, Select “CD-ROM, Check for Upgrade.
When the upgrade is finished, you can check the supported versions under Settings, Product Support Pack. In this case VIDM 3.3.5, vRA and VRASSC 8.4.1.
So far, so good! On to the next step and upgrade VIDM to version 3.3.5.
Unfortunately, the precheck returned two error Messages:
Disk space on / partition should be at least 3 GB for supporting upgrade. Current available space on / partition is 2.30 GB in node vidm.infrajedi.local
Disk space on /opt/vmware/horizon should be at least 7 GB for upgrade bundle upload. Current available space on /opt/vmware/horizon is 4 GB in node vidm.infrajedi.local
This is possibly caused by a different disk size and layout at first deployment time (I believe it was vidm 3.3.1).
Comparing the disk size and layout between my upgraded vidm 3.3.4 and a new 3.3.5 you can see the following differences (Note; I am using a small setup (with 2vCPU, 6GB RAM in my homelab):
The filesystem itself looks as follows:
root@vidm [ ~ ]# df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 2.9G 0 2.9G 0% /dev tmpfs 3.0G 16K 3.0G 1% /dev/shm tmpfs 3.0G 788K 3.0G 1% /run tmpfs 3.0G 0 3.0G 0% /sys/fs/cgroup /dev/sda4 8.8G 6.1G 2.3G 73% / tmpfs 3.0G 180K 3.0G 1% /tmp /dev/sda1 124M 30M 88M 26% /boot /dev/mapper/db_vg-db 9.8G 912M 8.4G 10% /db /dev/mapper/tomcat_vg-horizon 9.8G 5.0G 4.4G 54% /opt/vmware/horizon tmpfs 597M 0 597M 0% /run/user/0
Note the /dev/sda4 partition of 8.8G with 2.3G Available.
The summarized output from the fdisk -l command looks as follows:
Disk /dev/sda: 30.2 GiB, 32463912960 bytes, 63406080 sectors Device Boot Start End Sectors Size Id Type /dev/sda1 2048 272383 270336 132M 83 Linux /dev/sda2 272384 17061887 16789504 8G 82 Linux swap / Solaris /dev/sda3 * 17061888 33849343 16787456 8G 83 Linux /dev/sda4 33849344 52733951 18884608 9G 83 Linux Disk /dev/sdb: 10 GiB, 10737418240 bytes, 20971520 sectors Disk /dev/sdc: 10 GiB, 10737418240 bytes, 20971520 sectors Disk /dev/sdd: 10 GiB, 10737418240 bytes, 20971520 sectors Disk /dev/mapper/db_vg-db: 10 GiB, 10733223936 bytes, 20963328 sectors Disk /dev/mapper/tomcat_vg-horizon: 10 GiB, 10733223936 bytes, 20963328 Disk /dev/mapper/var_vg-var: 10 GiB, 10733223936 bytes, 20963328 sectors
There are various documents and kb articles out there (see below), but none was describing the exact instructions.
!!Note: I am not sure if the method below is supported. In case you are in doubt always contact VMware Support before you proceed.
- Shutdown the VIDM VM
- From vCenter, resize harddisk 1 from 30 to 50GB
- Take a snapshot
- Power On the VIDM VM
Install Parted with yum:
root@vidm [ ~ ]# yum install parted Installing: parted x86_64 3.2-9.ph3 photon-updates 1.12M 1170933 Total installed size: 1.12M 1170933 Is this ok [y/N]: y ... Complete!
After installation run the parted tool against /dev/sda and list the partitions with the print command:
root@vidm [ ~ ]# parted /dev/sda GNU Parted 3.2 Using /dev/sda Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) print print Model: VMware Virtual disk (scsi) Disk /dev/sda: 53.7GB Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End Size Type File system Flags 1 1049kB 139MB 138MB primary ext3 2 139MB 8736MB 8596MB primary linux-swap(v1) 3 8736MB 17.3GB 8595MB primary ext3 boot 4 17.3GB 27.0GB 9669MB primary ext3
Note the disk size of /dev/sda is now 53.7GB
The next step is to resize partition 4 with the resizepart command from parted:
(parted) resizepart resizepart Partition number? 4 4 Warning: Partition /dev/sda4 is being used. Are you sure you want to continue? Yes/No? Yes Yes End? [27.0GB]? 53.7GB 53.7GB
Check if your partition is resized with the print command:
(parted) print print Model: VMware Virtual disk (scsi) Disk /dev/sda: 53.7GB Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End Size Type File system Flags 1 1049kB 139MB 138MB primary ext3 2 139MB 8736MB 8596MB primary linux-swap(v1) 3 8736MB 17.3GB 8595MB primary ext3 boot 4 17.3GB 53.7GB 36.4GB primary ext3 (parted) quit Information: You may need to update /etc/fstab.
The final step is to resize the file system of the extended partition with the resize2fs command:
root@vidm [ ~ ]# resize2fs /dev/sda4 resize2fs 1.45.5 (07-Jan-2020) Filesystem at /dev/sda4 is mounted on /; on-line resizing required old_desc_blocks = 1, new_desc_blocks = 3 The filesystem on /dev/sda4 is now 8876032 (4k) blocks long. 597M 0 597M 0% /run/user/0
Check if the partition and filesystem changes are active and enough free space is available:
root@vidm [ ~ ]# df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 2.9G 0 2.9G 0% /dev tmpfs 3.0G 16K 3.0G 1% /dev/shm tmpfs 3.0G 792K 3.0G 1% /run tmpfs 3.0G 0 3.0G 0% /sys/fs/cgroup /dev/sda4 34G 5.3G 27G 17% / tmpfs 3.0G 180K 3.0G 1% /tmp /dev/sda1 124M 30M 88M 26% /boot /dev/mapper/db_vg-db 9.8G 1022M 8.3G 11% /db /dev/mapper/tomcat_vg-horizon 9.8G 4.9G 4.4G 53% /opt/vmware/horizon tmpfs 597M 0 597M 0% /run/user/1002
From vRSLCM, I re-ran the Pre-Check and this time there where no error messages (except about my cpu/memory sizing). Also no errors given for /opt/vmware/horizon, even if does not have at least 7 GB.
