Question

MongoDB backup error with volumegroup has insufficient space (0 extents)


Forum|alt.badge.img+4

Hi All,

I’m trying to backup MongoDB and already installed and configured for backup. When I run backup, there is issue of volumegroup no space.

When I run the vgs command, the volumegroup did have 0 free space. However the FileSystem (LVM) space have plenty of free space. Can we utilize the LVM free space for the native snapshot?

Other than adding extra disk to extend the volumegroup, is there anyway that I can backup the MongoDB?

Its a sharded MongoDB using ubuntu.

Regards,

Fauzi

Do you have at least 15% space available on the VG to hold the snapshot?  That is what is needed for snapshots in Linux.

Hi Orazan,

So I still need free space on VG not on LV? Do I need at least 5% as per documentation online or 15% free space of the VG?

The error I’ve got is for every node especially on the VG that hold the mongodata. Do I need to add extra space for every node? Do backup will be done from every node or how actually commvault backup the mongodb data? It is a sharded mongodb so it has replicas for each of the data for every node.

Fauzi

Hi there,

 

Did you ever figure out an alternative to extending the VG?

Hi,

My server team already add another disk and add to the vg. This is not supposed to be done because when they setting up the server should not use up the vg when creating lv.
