Hi Team, We having AFF8020 , version 9.7P22 (the support contract is done for this system) We've noticed already 3-4 times, that files disappeared (now we'll notice if it's happening every night, or once in few nights). The 1st time it happened, we've first created a clone from week ago snapshot to keep it in the side if the 'restore' won't work, and then we restored the original volume to few days ago, and the files got back. From the UI, I can't see something strange. But, now there is a strange thing, that I see that few new folders created/edited on the time 00:00. we didn't created it. it looks like some k8s/contect libraries directories maybe. don't know     So I suspect it's one of 2 things : 1. something related to snapshot etc. 2. maybe there is some system that this volume is mounted to it, and it's doing some changed in 00:00. but I can't see it from the UI logs     I do saw some similar topic here :https://community.netapp.com/t5/Ask-The-Experts/Files-disappear-from-NetApp-2220-every-day-at-00-00/td-p/153164 So I'm already showing here the command that the supporter asked there.   ** editing -  I see both on May 22, and May 30, the following error on the "event log show"  5/30/2024 00:03:58 ntn01-netapp01-b ERROR disk.dynamicqual.fail.parse: Device qualification information file (/etc/qual_devices) is invalid.

Hi Team , we're using physical used capacity to compute various metrics. We've observed that for some volumes, the used capacity and physical used capacity values are the same, while for others, they differ. Here are the details from our NetApp system (version 9.13): ``` A250::> volume show -fields size, available, total, used, physical-used vserver volume      size     available  total    used     physical-used ------- ----------  -------  ---------  -------  -------  ------------- A250-01 vol0        151.3GB  72.74GB    143.7GB  70.99GB  68.25GB A250-02 vol0        151.3GB  77.03GB    143.7GB  66.70GB  62.60GB svm1    Lun_1       2.06GB   2.06GB     2.06GB   632KB    632KB svm1    Lun_test_3  10.30GB  10.30GB    10.30GB  692KB    692KB svm1    svm1_root   1GB      970.3MB    972.8MB  2.48MB   7.96MB ``` We've tried to understand the reasons behind this discrepancies but couldn't get a clear explanation. Could you please help us understand about this  volume capacity values. Thank You ! ... View more

Hi all,   I having an issue on space discrepancies between storage LUN and end host space (LUN that mapped on windows server). After go through some research, I found out that required to enable the space allocation on thin LUN to make host-side space management identifies blocks of data that have been deleted on the host file system allow ONTAP to reclaim space. I've already enable the setting for space allocation and just want to ask few asking here after we enable the feature.   1) After we enable the space allocation feature/setting in the LUNs and already verify the features is already enabled, how long can we can expect to see the reflect of space on the storage LUN will align/tally with the space available in the host end?   Please advise as I need to understand what the result we can expect after enabled the space allocation feature.
