ZFS ZFS Dataset is Occupying More Space than the Actual Data

[Senthilnathan]

One of the zfs dataset in the server is occupying more space than the actual data present in it. Actual data used in that dataset is 2.7TB but the property 'used' is showing as 5.18TB which is more that 100% . Pool configured as raidz2 (4+2 disks)

This dataset is transferred from another pool to this pool 'tank' using zfs send/recv and now the old pool is not present in the server.

Need some experts advice on how to fix this dataset.

Actual data present in the volume is:

Lots of files much smaller than the block size? "logicalused" looks quite sane.

 

[RoGeorge]

There might be older snapshots keeping the space occupied.

If, let's say, at some point you have a 4GB file file_big.iso copied on your zfs disk, take a snapshot, then a month later you delete the file_big.iso, those 4GB will still be kept as used space, until you delete that old snapshot from last month.

When deleted, a file is not really removed from ZFS, and the space is not freed if that file was present in any existing snapshots. ZFS will keep that space reserved, just in case you'll want to access one of the former snapshots that used to include the now deleted file.

Have you checked for older snapshots?

 

[Cath O'Deray]

There might be older snapshots …

With usedbysnapshots 0?

<https://openzfs.github.io/openzfs-docs/man/7/zfsprops.7.html#Native_Properties>

 

[Cath O'Deray]

… occupying more space than the actual data …

My first thought was, maybe sparse something, which led me to a comment under ZFS: usedbydataset value unusually large on one zpool - Server Fault (not yet answered).

 

[Andriy]

sparse something

that does not use disk space

 

[zirias@]

The full property listing in the OP already shows there's no space used for snapshots or child datasets, so tons of small files is the only possible reason I can see here...

 

[Senthilnathan]

Thanks everyone for sharing your thoughts.

There are no snapshots for this dataset. This dataset is transferred from another pool, so I thought old snapshots or data could be in pool cache, so rebooted the server in order to clear the pool cache but still the dataset is showing used space as '5.18T' but the actual data present is only 2.7T which has some iso files and other files.

How to fix this dataset to have the used space approx 2.7T ?

 

[Andriy]

Why don't you read what Zirias said? And get some stats on file sizes...
To add, the difference between the two pools can be in ashift.

 

[Andriy]

old snapshots or data could be in pool cache

For ZFS newbies reading this thread: that's just nonsense.

 

[covacat]

do a df -i /vol2

 

[Cath O'Deray]

5.18T written.

Replication

For the four replication:⋯ properties, is any value relevant?

To the best of my recollection, I never used the feature, but this (unanswered from months ago) catches my eye:

… Where are the discrepancies coming from? Why does it report 330 MB written, while expecing 110 MB to transfer via zfs send and actually transferring 720 MB. There are many question marks here …

Retrospective

… now the old pool is not present in the server. …

Were you the owner/manager of the old pool?

Is it possible that copies was 2 during some period long ago, might something like this explain the apparent discrepancy?

Was the old pool imported read-only at the time of send?

 

[Senthilnathan]

Were you the owner/manager of the old pool?

Certainly not. This dataset transfer was done a year ago and the used space difference is noticed by me recently in the server so this becomes my headache now.

There were no small files resides in this dataset. On the other end, this dataset is mounted in the vmware server and some VM's are running in it.

Here is the inode usage and disk usage breakdown,

I don't know the answer for this question. However, after a recent server reboot 3 days ago , I am seeing the written and used is now showing as '4.89 T' which is somewhat low from the output shown in first post . Can't figure out what is happening in this dataset and there is no additional data added to it.

Is it possible that copies was 2 during some period long ago, might something like this explain the apparent discrepancy?

looks so
try

find /vol2 -type f |xargs stat -f "%SN %z %b 512"|awk '{printf "%.2f %s\n", $3*512/$2 ,$1}'

script displays blocks*512/size
see if you have many files with 2+ usage
here is output of /usr/bin/* copied on 2 datasets with copies 2 and 1
both datasets with 128k recordsize

[Senthilnathan]

looks so
try

find /vol2 -type f |xargs stat -f "%SN %z %b 512"|awk '{printf "%.2f %s\n", $3*512/$2 ,$1}'

script displays blocks*512/size
see if you have many files with 2+ usage
here is output of /usr/bin/* copied on 2 datasets with copies 2 and 1
both datasets with 128k recordsize

I couldn't paste the complete output which exceeds the characters rule so, providing few things below where output of the script ran under vol2 without awk. By seeing the output, you can see why awk doesn't work in this scenario,

covacat I have furnished the output of your script. Looks like there are no files with 2+ usage, could you please check the script output?
