This is the third post in the “Space reclamation” series focusing on Linux.
Like in Windows and in VMware ESXi also in Linux dead space is left behind when data is removed.
For space reclamation under Linux there is available a Linux version of EMC StorReclaim with same options as Windows version.
To get EMC StorReclaim contact your EMC representative.
With newer Linux operating systems there is a native trim operations available to get back unused space. I will write about trim in the future when I have had more time to test it.
If anyone knows more tools that can be used to reclaim space in Linux please let me know in the comments sections.
