How to extend the datastore size

[parker0909]

Hi All,

I just setup the new Proxmox Backup Server for testing. I have created the datastore as below command. May i know it possible to extend the size when i already add more disk space in the hypervisor level for this disk?

# proxmox-backup-manager disk initialize sdb
#proxmox-backup-manager disk fs create store1 --disk sdb --filesystem xfs --add-datastore true

I checked that the datastore just any sample disk type without any LVM. May i know any suggestion for extend the size for backup datastore. Thank you.

Regards,
Parker

you can extend the filesystem/partition that backs the datastore it like any other Linux filesystem/partition.. (e.g., for VM disks, check out https://pve.proxmox.com/wiki/Resize_disks )

Thank you. i tried to Resize the disk by parted.but it seem the size still not grow. I tried to use xfs_growfs command to enlarge the size but i got the warning should be "/dev/sdb1 is not a mounted XFS filesystem". Thank you.

what does mount say in the VM?

 

[parker0909]

Thank you. This is the result showing in mount command

/dev/sdb1 on /mnt/datastore/store1 type xfs (rw,relatime,attr2,inode64,logbufs=8,logbsize=32k,noquota)

xfs_growfs expects the mount point, not the block device.
