I am trying to test a disk space monitor we have setup.
For that purpose, I ran
truncate -s 125G /publish/data/bigFile which should claim enough space for the alert to be triggered.
However, df -h shows for that partition:
/dev/vdb1 196G 66G 121G 36% /publish/data
(which is to say, free space has not changed after running the truncate command.)
ls -lh on the file shows:
-rw-r--r-- 1 username users 126G Aug 7 11:27 /publish/data/bigFile
mount output for /publish/data:
/dev/vdb1 on /publish/data type ext4 (rw,relatime,data=ordered)
Edit: I also just realize, the numbers do not make sense: 196-66=130gb, so why df says 121gb free in the first place?
