Top Forums UNIX for Beginners Questions & Answers Safe way to shrink lvm vg_*-lv_swap partition and reclaim freed space on Linux? Post 303039341 by gull04 on Tuesday 1st of October 2019 09:08:43 AM

Hi,

On Centos 6.10 and RHEL 6.10 in the lvreduce there is also the -r, --resizefs switch. This would allow things to be done in a single command line.

Please note if the system is swapping/paging the command will possibly take along time.

It should also be noted that reducing the swap can be done to an absolute value or by a specific amount, please read the man page and if possible test to ensure you get the expected result.

Regards
