Hi WidoThank you. Yes, I only shrink it inside the VM. But still Cloudstack volume shows 120GB and within the VM lsblk command shows that 120 GB is available. Since I cannot shrink the volume, how do most providers take care of this issue? I mean it would be awkward if a client see they can have 120 GB available when they're paying for 60 GB, for example.

Rebooted via and detatched the ISO and now VM shows 60 GB correctly. However, in Cloudstack, still says the volume is 120 GB. But when I want to shrink it to 60 GB, I get this error:In this case you did not shrink the volume, but only the partition and filesystem on the volume.Failed to resize volume operation of volume UUID: [eec8285e-8715-441b-b418-b71b231f1bab] due to - Unable to shrink volumes of type QCOW2QCOW2 volumes can't be reduced in size. So no, this is not a bug.And yes, the VM is stopped when I try doing this. I now want to confirm from the community, is this the expected behaviour or not? It seems Wei doubted it. If not, that means I have a bug that need to be looked at and further checked.Wei is correct. QCOW2 can't be shrinked.

You did this resize manually outside the knowledge of cloudstack, am I correct?How did you do this live/recovery method?

However, now in Cloudstack it still says the volume remains 120 GB and when I want to shrink it I am presented with the errors from my previous reply. Is there a way around this? Such as making a database change. Also, is this the expected behaviour for a KVM host?This is recorded in the table 'volumes'. If you decrease the size to 60GB there is should show properly.WidoOn 9/2/23 11:22, Granwille Strauss wrote:Hi Wei It seems you're right you cannot shrink the volume in Cloudstack:Failed to resize volume operation of volume UUID: [eec8285e-8715-441b-b418-b71b231f1bab] due to - Unable to shrink volumes of type QCOW2Going from existing size of 128849018880 to size of 64424509440 would shrink the volume.Need to sign off by supplying the shrinkok parameter with value of true.On 9/2/23 10:37, Wei ZHOU wrote:Hi Wido, Does it work with kvm ? my suggestion would be - create a new vm with 60GB - copy the data using `rsync` -WeiOn Sat, 2 Sept 2023 at 08:25, Wido den Hollander<w...@widodh.nl> wrote:Hi,Yes, you should make sure the filesystem and partitions are within theto be set new boundaries. Once that's done you can shrink the volume. I would recommend: - Shrink EXT4 + Partitions to 59GB - Shrink volume to 60GB - Grow EXT4 + Partitions to 60GBThe step to 59GB is to prevent that by calc mistake you chip off thelast portion of your filesystem.

What's the best and recommended way to shrink a VM volume via UI? The VM volume was first 60 GB, we then expended it to 120 GB and increased it in the VM via parted. I now want to take it back to 60GB. How do I proceed? Do I first shrink the ext4 in the VM first then proceed to shrink the volume in Cloudstack UI by selecting also the "Shrink OK" option? Detailed steps would beappreciated, please. -- Regards / Groete<https://www.namhost.com> Granwille Strauss // Senior Systems Admin*e:*granwi...@namhost.com *m:* +264 81 323 1260<tel:+264813231260> *w:*www.namhost.com <https://www.namhost.com/> <https://www.facebook.com/namhost><https://twitter.com/namhost><https://www.adsigner.com/v1/l/631091998d4670001fe43ec2/621c9b76c140bb001ed0f818/banner<https://www.adsigner.com/v1/c/631091998d4670001fe43ec2/621c9b76c140bb001ed0f818Namhost Internet Services (Pty) Ltd, 24 Black Eagle Rd, Hermanus, 7210, RSAThe content of this message is confidential.
