After removing many files at once system stops responding.

[moskyt]

Hi,
I have a big problem with removing files on my FreeNAS.
With removing a lot of files at once the system stops responding immediately. Reboot is necessary.
I've never seen this behaviour before. It started with the new 11.2 version.
Any idea what can cause it?
Thanks.

Details please!

What hardware? What were you doing? Is this a SMB or NFS share?

 

[moskyt]

HP Micro Server Turion II NEO N54L
8GB RAM
Mirror 2x3TB WD Red
SMB and NFS shares are not configured right now.
I am deleting files in my SSH session directly on the system.

Example:

Code:

root@freenas:/mnt/storage/Backup2 # find MP3/ | wc -l		   <- directory with more than 3000 files
	3430
root@freenas:/mnt/storage/Backup2 # rm -rf MP3/				 <- trying to delete

- after this command system stops responding. Cannot even ping IP. Total freeze.
Tested on other directories and filesystems. The same problem.

I'm following interested, since I'm facing the same issue... couldn't find any answer for the moment...
same machine as moskyt, HP N54L + 8Gb RAM, 2*2TB WD Red (mirror raid)...

11.2 is not stable. At best it's beta. Suggest you roll back and see if you still have issues.

We need more details. Is encryption used? Dedup?

thanks, I'm a newbie with FreeNAS, can you pls tell me how can I rollback to 11.1?
Not even sure I first installed 11.1 rather than 11.2 beta (and I was told by FreeNAS GUI about an update to 11.2 "stable" which sounded strange to me tbh)

@wblock: no encryption, no dedup. simple zfs pool created after first setup, only installed BackupPC (then removed) and Plex Server
that's all

No encryption, No deduplication, No compression.

Code:
