more than 100% disk usage

[Aktar Alam]

HI All,

I have been facing a weird issue of disk usage being more than 100% usage.
Currently the df -h shows:
/dev/ad1p1 902G 902G -72G 109% /mnt/backup
/dev/ad2p1 902G 882G -52G 106% /mnt/backup2

I am new for all this, sorry in advance if its silly.
But is problematic and I dont understand from where it shows free space in negatives.

Also I have a server whose entire data size is around 450GB and the backup disk I am using on freenas is 1Tb but still within 2 months the 1 TB gets full.

Would be great favor if any one can guide me.

df is probably not the best tool to use since it dones't understand ZFS. I would suggest using zpool status to see your disk usage.

Those are UFS partitions. UFS reserves some space (about 10%) for frag management. Root can use that space anyways, so it is correct that you've used 109% of the space available to users. Delete about 80GB.

Hi jgreco,
Thanks for your reply...

I deleted 96 GB folder but it happened in fractions of second [ which I doubt whether the files are deleted but I cannot find the files which means they would have been deleted.]


commands I executed are:
[root@server bak_dbtoolkit]# du -sh *
96G DB_backup
***
***

[root@server bak_dbtoolkit]# rm -rf DB_backup

But the disk space utilization is still 109%

/dev/ad2p1 902G 902G -72G 109% /mnt/backup2


Thanks in advance for further guidance.
