FLR - Date Accessed

I have FLR-E enabled Filesystem in a VNX5200 File. Retention is set to 30 years via FLR Monitor. After archiving files to the FLR Share under the file properties the FLR Attributes shows the correct Date (March 29, 2046) and that the File is locked. But when I look in the Generel Tab the "Accessed" Date is "March 29, 1978". Other files show 1910.

Is that Correct?

Re: FLR - Date Accessed

Thanks for the hint,

but I can not find the mistake I have made.
FLR Monitor is running and locking the files as soon as they are copied on to the share.

I tested more and found out that when I set the retention to 20 Years the "Date Accessed" ist shown correct, 2036.

But when I set it to more the 24 Years the Date becomes 1978. So it looks like the date was set to infinite for some reason.

What am I doing wrong?

Re: FLR - Date Accessed

this really smells like a problem with the Unix 32 bit date ending in 2038

Support for Retention Dates beyond 2038 was added in VNX OE 7.1

what versions of VNX OE and the FLR toolkit are you using?

my advice:

check what your epoch date is set to - see nas_fs

maybe your fs was created with an older VNX OE Version like 7.0 ?

could be problem with FLR monitor in setting the date or just in displaying it

check the FLR log on the file system itself - it is authorative

P.S.:

Instead of the manual linked above please use the latest VNX OE Manual Jyothi quoted is from an old version that doesnt support retention beyond 2038

Re: FLR - Date Accessed

Hi,

I'm using latest FLR Monitor 4.1.1.25 on Windows 2012R2

NAS Version 8.1.3-79

Epoch Year is set to 2003

I have changed the Epoch Year to 2016 and also to 2037 but the Date ist still 1978, so I changed it back to 2003

When i check the Files with #ls -l --time-style=full-iso --time=atime

-r--r--r-- 1 32768 32771 6 1978-04-04 11:40:28.000000000 +0100 test - Copy (10).txt

-r--r--r-- 1 32768 32771 6 1978-04-04 11:40:28.000000000 +0100 test - Copy (11).txt

-r--r--r-- 1 32768 32771 6 1978-04-04 11:40:28.000000000 +0100 test - Copy (12).txt

the Date is not correct

FLR Log states the following: (I have also listed the Inode Number)

Re: FLR - Date Accessed

the fact that an ls will show an "incorrect" value is normal and is because the date store inside the file system is still 32 bit - just interpreted with the epoch as an offset for FLR purposes.

If you want to see the effective FLR date you need to use the FLR Tools or look at the log

The FLR log is what is authoritive.

Also - be aware of what changing the epoch on existing locked files does.
