Don´t show me hour when creating file in filesystem mounted NFS

[Claudemir Franco]

Hi,

I have a problem, when I created(way touch, vi and cat) one file in the filesystem mounted way NFS, don´t show me the hour the file created.

Note: This filesystem is mounted way NFS of the one NAS.

Thanks.

Claudemir.

What does it show? An 'ls -l' listing of the file would be helpful.

Other information that would be helpful: HP-UX version, NFS version, tcp or udp

Do you have the latest NFS patches for whatever version of HP-UX you are using?

[Claudemir Franco]

I attached the file with the information request. ;o)

tks

Note that your ls -l display would be perfectly normal if the system date were somehow off. Post the output of the date command and the output of "locale LC_TIME".

[Claudemir Franco]

The output is:

sgfho02:/prodbrt# date
Tue Apr 17 18:15:42 SAT 2007
sgfho02:/prodbrt# locale
LANG=
LC_CTYPE="C"
LC_COLLATE="C"
LC_MONETARY="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_MESSAGES="C"
LC_ALL=


This is correct?

Okay, let's determine if this is an ls problem or something more fundamental such as the stat() system call returning bogus data.

perl -e '$a = (stat("/xxx/yyy/filename")) [9]; print scalar localtime($a),"\n";'

This will print the modification time of file /xxx/yyy/filename in the same format as the date command.

[Patrick Wallek]

What type of NAS system is the NFS share exported from? What OS does it run?

[Claudemir Franco]

Stephenson,

okay, take a look in the output command line:
sgfho02:/home/root# perl -e '$a = (stat("/xxx/yyy/filename")) [9]; print scalar localtime($a),"\n";'

Wed Dec 31 21:00:00 1969

thanks a lot of

Earth to Claudemir:

Replace "/xxx/yyy/filename" with one of your NFS mounted files. For comparison, I would also try one of your local files.

[Sandman!]

Is this localized only to that particular NFS mountpoint? What happens when you create a file similarly on a local filesystem?

[Claudemir Franco]

Stepheson,

I´m so sorry....I am sleeping (heheeh)...

sgfho02:/prodbrt# perl -e '$a = (stat("/prodbrt/trash1"))[9]; print scalar localtime($a),"\n";'

thanks.


Sandman,

In filesystem /tmp show me hour when I created file, for i.e.

C.

[A. Clay Stephenson]

OK, something appears strange to me. When I had you run the date command earlier and I compare it to the Perl display of the files mtime, it seems (and doing a little math about the times of postings) that you have created a file newer than the system time. ls -l is behaving exactly right. This was pilot error and the "problem" will magically "fix" itself when the system time catches up with your file's modification time.

This could also be caused if the NFS server and client are not running NTP and the times are not in sync. It is vital that these systems synchronize their times (even if running in different timezones because the systems keep time in seconds since 00:00:00 1-Jan-1970 UTC) or chaotic behavior will result.

It appears that my original hypothesis was correct.
