RE: Two files with same name under NFS
by Rudie, Tony 11 Nov '99

11 Nov '99

You can cause this to happen if you mv (and perhaps cp) a file from a snapshot back into the main filesystem, if the file already exists in the main filesystem. the approved method is to remove the one in the main filesystem first. I'm a sissy, so I prefer moving the original to some other name, then copying in the one from snapshot, then removing the renamed original. -----Original Message----- From: Stephen C. Losen [mailto:scl@sasha.acc.virginia.edu] Sent: Thursday, November 11, 1999 1:49 PM To: toasters(a)mathworks.com Subject: Two files with same name under NFS We are running ONTAP 5.2.3D1 in a mixed CIFS and NFS environment. Recently we encountered a directory that had two different files with the same name under NFS. This was reported by ls -ali | grep NEW 1176207 -rwxr-xr-x 1 1224 1224 674 Nov 10 10:32 NEW2.GIF 3907524 -rwxr-xr-x 1 1224 1224 674 Nov 10 10:32 NEW2.GIF Yes, we checked very carefully and there are no spaces or other unprintable characters in the names. Not trusting "ls" I even wrote a little perl script that calls readdir to print out the filenames and they are indeed identical. Actually, this ls output is erroneous because the two files have different permissions and mod time. Still, this does show the different inode numbers, indicating two distinct files. From W98 you can see these are two different files. One is named NEW2.GIF and the other is named NEW2~0.GIF. And the mod times are indeed different. So I conclude that we have a filename mapping problem where two different files map to the same NFS name. Is this a normal situation that should be expected periodically, or should this "never happen"? We know that under NFS you can create two files with the same spelling but different capitalization, but these are not allowed under CIFS. So when a NFS dir containing such conflicts gets converted to CIFS, the filenames are "massaged" by having ~number appear in the CIFS name. However, we couldn't come up with a repeat-by where we could create two files under CIFS with the same NFS name. Anyone else figure out how to do it? Also, once you have a situation like the above, it seems like it's a toss up as to which of the two files you see under NFS. Running ls -li NEW2.GIF on one NFS client showed one of the inums while running the same command on another NFS client showed the other. So this could cause confusion.

For mail systems with small mailboxes I would expect that "10" might be higher than optimal. If you message store is one file per message and most messages are small, I would actually expect performance to be marginally worse with nfs_nra = 10 than with a lower value. I'd hesitate to speculate on what would be optimal without knowing the specific characteristics of a particular situation. > The default value for > this appears to be 524288! This would be several Gigabytes in size. In some situations, automatically loading in the whole file might be a good thing. In some situations, especially where the client connection was very slow, it might read the whole file into memory, but be so slow about sending the connection down to, say, a POP client that LRU caused some of this info to be flushed from the buffer cache before it got transmitted, in which case it would have to be read again, which would be a waste. > Since there are other applications that > suggest tuning these parameters, and Sun asks us to change them from time > to time, it is helpful to know 'why' we set the values.

In most cases, this is probably the case. Note, though, that if your servers are memory poor the same parameters that work best on a similar machine with memory to spare are likely to be sub-optimal, for example. > FYI, here is the list of things we got from the salesperson: > ---- > set npty = 1024 > set nfs:nfs_nra = 10 > set nfs:nfs3_nra = 10 > set nfs:nfs_max_threads = 24 > set nfs:nfs3_max_threads = 24 On really busy mail servers with much memory, my opinion is that nfs_max_threads can be set much higher than this. I believe that one thread per concurrent process accessing data over NFS is not unreasonable as a rule of thumb, as long as the box doesn't start thrashing as a consequence. > set maxusers = 256 Depends on your box and how much RAM you use. For E250, E450, E3500, and larger servers, boosting this to 2048 is not unreasonable if you have RAM to burn in order to gain performance. > set ncsize = 30000 If you don't have one of the patches listed above applied, this may be a little too high.

The nature of the message store is important. The load characteristics are important. What client machines are being used and how much RAM do they have? Is it worth consuming more memory, network, and filer I/O resources to reduce POP or IMAP connection latency? Is the system primarily a POP, file based, or IMAP server? There are a large number of variables that precludes a simple answer. In everyone's case, there's not much to do about it except to understand what the parameters do and to iterate on them until good things happen. In order to understand what they do, I recommend the 2nd edition of Adrian Cockroft's Solaris performance tuning book and the SMCC NFS Server Performance and Tuning Guide from Sun. For the latter, it's a matter of time and effort. However, for those sites managing less than 100,000 mailboxes, the return on lots of careful tuning is probably small enough that it's not worth pursuing. One note of caution, Cockroft's book covers Solaris tuning up through about Solaris 2.5.1. While the descriptions are still valid, some of the math and parameters have changed. Not all the advice is good advice if you're running Solaris 2.6 or higher. The same would be true for older editions of the Tuning Guide. -- Nick Christenson npc(a)sendmail.com

One of my main complaints about the current fcal implementation for the filers is that there is no visual indicator of loop status. I know NetApp is working toward addressing this, but it would have been nice to have from the start. I wish fcal were more like token ring or fddi and that the loop were "self healing". When I had an LRC fail on an fcal shelf, there was no way of finding which LRC (used process of elimination) was the culprit, as the entire loop was offline, not just the failed shelf and those after it.

Fast ENet cards for F330 and F540

Hi All - We've got two toasters, a F330 and F540. They're currently networked with FDDI, but we would like to migrate to 100BaseT. NetApp has EOL'd these models, even thought they're three years old, and does not sell these parts. Anyone have suggestions for finding an alternate vendor for NetApp NICs? Or a recommendation for a used/surplus dealer? Thanks in advance. -warren Warren M. Walsh Honeywell Technology Center 612-951-7837 walsh_warren(a)htc.honeywell.com

Failure of rm -rf

09 Nov '99

Since we moved to 5.3 (actually 5.3.2R1P1) we see occasional failures in various Unix automated management procedures. I've finally traced this to the "rm -rf" command failing. On Solaris systems it fails with: rm -rf /<filer>/x rm: Unable to remove directory /<filer>/x/y/z: File exists On SGI systems the slightly more meaningful error message is /<filer>/x/y/z: Directory not empty However, just repeating the rm -rf command once more works perfectly and the directory tree has gone. I don't think it's anything to to with CIFS file locking since some of the directories are old and have not been used for a long time. Has anyone else seen this?

Does anyone know if it is possible for a cluster of Macs to see a filer? If that's not possible directly, do you know of any free-ware or not code that would allow it? Anyone here had experience in doing something like that? Cheers. -- Yann Golanski Internet Systems Developer yann.golanski(a)theplanet.net The Planet Online

A colleague is going to be instigating testing of all the players for sharing data to NT systems and Unix, soon, so I've gotta go, haven't I?

RE: Legato Clienk Pak for Netapps

Hi Scott, > Just received the new client pak for Netapps. Much to my chagrin, I find > out it doesn't support the F500 series filers. Anyone know why this is the > case? Its due to bug 13252, a description is online. Unfortunately, we had a strange JVM/platform interaction: Under Data ONTAP Release 5.3 or 5.3.1, running NDMP or other Java-based software on F520 or F540 systems can cause system panics or watchdog resets due to an interaction between the Java runtime environment and the F520/F540 hardware/firmware. This has been resolved in Data Ontap 5.3.4. Legato are going to certify 5.3.4R1, due in a few weeks, with the Client Pak, which will then also support F500 series filers. Cheers, Grant -----Original Message----- From: Scott Mikusko [mailto:guerilla@concentric.net] Sent: Thursday, November 04, 1999 12:14 PM To: toasters(a)mathworks.com Subject: Legato Clienk Pak for Netapps Comrades, Just received the new client pak for Netapps. Much to my chagrin, I find out it doesn't support the F500 series filers. Anyone know why this is the case? And after upgrading all my systems to 5.2.3 three weeks ago, I find out I need to upgrade to at least 5.3.2. Lovely. And I see that the client does not allow backups of the snapshots, which is what I'm currently writing to tape. Apart from these annoying issues, what does anyone have to say about the client software for the Netapp? I have a system here that is taking nearly 40 hours to do a full backup, and 20 hours for incrementals to backup via NFS mounts to the backup server. I'm hoping that the client pak will help improve the time it takes to get my filers backed up. The filers themselves are not too terribly busy, I just have very large file systems. Anyone have any stats on the performance of the client software vs NFS mounting the filers to a backup server? Curious.
