Storage

Can I grow block storage?​

Yes, but it cannot be shrunk.

  1. Stop the VM.
  2. On the Block storage detail page, Edit > Change size > Save.
  3. Restart the VM; the filesystem expands automatically.
df -h  # Confirm the expanded capacity

For details, see Block storage resize.

You can also leave the existing disk alone and attach an additional empty disk to expand capacity. The new disk can't share a mount point with the existing one. The procedure is in Attaching an additional disk in the block storage guide.

I can't create more block storage because of the quota​

When your organization's block storage quota is exceeded, creation and resize are rejected.

  1. Check the currently allocated block storage quota under Infrastructure > Resource Status.
  2. Free up space by cleaning up unused storage, or request a quota increase via Support.

rclone won't connect to object storage​

The --s3-no-check-bucket option is most likely missing.

ECI object storage does not support creating buckets through the API or checking for existence. When using rclone, always pass this option.

rclone copy ./data elicecloud:YOUR_BUCKET/data --s3-no-check-bucket

Also confirm the endpoint URL is correct. The endpoint varies by environment — use the value shown on the Access info screen displayed right after creating the object storage user.

df -h shows odd capacity after mounting PFS​

VAST NFS-based PFS may show a synthetic large number in df -h rather than the cluster's actual capacity. This is expected.

Check the actually allocated capacity on the parallel file system detail page in the portal.

PFS won't mount after rebooting the VM​

When the kernel version changes, the previously built vastnfs driver may not match the new kernel, so the mount can fail after a reboot.

Reinstall the driver with the commands below.

sudo apt remove -y --purge vastnfs-dkms

VASTNFS_VERSION="4.5.5"
cd /tmp
wget https://vastnfs.vastdata.com/version/$VASTNFS_VERSION/source/vastnfs-$VASTNFS_VERSION.tar.xz
tar -xf vastnfs-$VASTNFS_VERSION.tar.xz
cd vastnfs-$VASTNFS_VERSION
sudo ./build.sh bin
sudo apt install -y ./dist/vastnfs-*.deb
sudo update-initramfs -u -k $(uname -r)
sudo vastnfs-ctl reload

cd /tmp && sudo rm -rf /tmp/vastnfs-*

Does restoring from a snapshot overwrite my existing data?​

No. Restoring from a snapshot creates a new volume. The existing volume is unchanged.

In Block Storage > Block Storage, click Create Block Storage, pick Snapshot as the disk type, and choose the snapshot to restore — a new volume containing that point-in-time data is created. The list of volumes restored from a given snapshot is shown under Block storages created from snapshot on the snapshot detail page.
