RE: Snapshot reserve management
by Hill, Aaron 10 Dec '03

10 Dec '03

At on stage, I ran into this frequently with large databases & batch processing areas combined with snapmirror across an inadequate WAN pipe. Expert internal advice and intimate knowledge of the database rebuild & batch scheduling matrix still only provided partial knowledge of which block changes were coming from where. Various nfsstat scripting/logging helped identify which servers were committing the most nfs ops, but there was not much we could do about it even with that information. Management involved the snapshot deletion method, some late nights, temporary bandwidth upgrades and ultimately some disk purchases. None of it could be honestly described as prevention. This has changed in my current environment. We currently use 2 tools; DataFabric Manager - our "project" areas a split into hundreds of qtrees that can be monitored individually. Any large usage increases/decreases in a particular area can be pinpointed. Intermine Filecensus - With this we can quantify file/folders that have been created/modified/accessed. Filecensus can even be configured to scan snapshot areas if you want to compare between snapshot and current content. I must note that we do not really have the same snapshot problem in the current environment. But I can see how DFM and Filecensus output could be produced to help track down "paths" that are making the largest contributions to filesystem change. Hope I have added more answers than questions! Aaron -----Original Message----- From: Brian Tao [mailto:taob@risc.org] Sent: Wednesday, 10 December 2003 2:10 PM To: toasters(a)mathworks.com Subject: Snapshot reserve management I think most any Netapp admin has been in this situation: you set aside a chunk of disk space for your snapshot reserve. After a week goes by, you see that the reserve is at 150% of allocation. You manually delete some snapshots until it falls back under 100%, and adjust the snap schedule. A few months go by, new applications are rolled in and old ones retire. Snapshot usage has also increased, but you are at a loss to pinpoint the exact cause of the higher data turnover rate. What do people do to shed more light on this kind of situation? I'd love to be able to conclude "It is the files in /vol/vol0/myapp/data that are chewing up the most snapshot space" or "It is the write activity coming from NFS client myhost1 that is causing the most block turnover". I think I asked this question about five years ago and did not discover an adequate solution back then. I'm hoping someone might be able to share their expertise on this problem now. ;-) -- Brian Tao (BT300, taob(a)risc.org) "Though this be madness, yet there is method in't" ************** IMPORTANT MESSAGE ************** This e-mail message is intended only for the addressee(s) and contains information which may be confidential.

Netapp F760
by mikka makka 10 Dec '03

10 Dec '03

Hi all, I've inherited a Netapp F760, with two FC9 shelves (7x36 GB FC disks). I noticed some discussion earlier on this list about Netapp having a "hobbyist" program, whereby home users could get software updates and license keys for unsupported machines. (Mine is working fine, but only has NFS licensed -- I'd like to experiment with CIFS, HTTP, etc.) Does anyone have any more details about this? I searched the Net but was unable to find any specific information, other than that various people seem to have successfully gotten hobbyist license keys from their Netapp reps. (I don't have a Netapp rep, since I am only a home user). Also, my unit has two broken disks -- one was bad when I got it, and another failed (urk) shortly thereafter. I am curious whether I can simply take a new, empty Seagate ST136403FC disk -- this is the same model number as those in the system now, remove the failed disk from the drive carrier, and swap in the new one? That is, is there anything special about a NetApp-spec disk (special firmware maybe, or something prewritten on the disk, or whatever) that differentiates it from a generic Seagate disk, and would therefore prevent me from using it in the system? If so, is there any workaround? Thanks a lot for any info, Mikkamakka _________________________________________________________________ The new MSN 8: advanced junk mail protection and 2 months FREE* http://join.msn.com/?page=features/junkmail

F760 SCSI, Single-ended or Differential
by Harold White 09 Dec '03

09 Dec '03

Greetings, I just noticed that my F760 displays, what I believe to be, its on-board external SCSI port as "Fast/Wide, Single-ended" F760> sysconfig -v NetApp Release 6.4R1: Thu Mar 13 22:59:45 PST 2003 .... slot 0: SCSI Host Adapter 0b (Qlogic ISP 1040B, <ONLINE>) Fast/Wide, Single-ended Firmware Version 4.66.00 Clock Rate 60MHz. 4: Tape: Quantum DLT7000 245F 5: Tape: Quantum DLT7000 245F ..... I am/was under the impression that it was a Fast/Wide Differential (on-board) SCSI controller. I have 2 DLT7000 drives connected to the Filer ... and they are absolutely differential (2 drives from a Sun L1000). My Veritas Datacenter software keeps down'ing one of my drives and I have just ignored it due to time constraints plus the fact that I had/have one good drive still working. But now that I am trying to troubleshoot the problem, I do not know if the problem is that I have been lucky that a "Single-ended" filer controller has been providing me good backups to my differential (one) tape drive? (Is that even supposed to work at all?) Can anyone confirm that the output (sysconfig -v) of a F760 "Single-ended" is correct or incorrect? That is, is the on-board external SCSI port a differential or single-ended SCSI port and the "sysconfig -v" message is right or wrong? Regards, Harold White Covaro Networks

Hi all i am newbiew to filer and storage , i am eager to know following things but unfortunately m not been able to get the rite pointers which can describe the stuffs in detail 1) How exactly the Fiber Channel works ? what are the stuffs involves in setting up a SAN using a Fiber Channel and what are their functions in details along with the alternative devices that too supports the same functions and can be used 2) what is the purpose of space reservation as far as Netapp's Filer FCP support is concern , why people need space reservation for volumes,qtrees or for luns ? 3) what size of volume i need to have if i want 1 TB of lun ? i have read in docs that i should i have atleast 2-3 times volume size if i wanna have lun on the volume that is for 1 TB of lun i need to have 2-3 TB of volume , where the other storage space being used ? 4) what would be the usable lun storage capacity if i create lun of 1 TB ? how much space will get utilized for partition table and keeping file systems metadata ? 5) is it possible to install more then one HBA's on hosts like solaris , windows mechines ? -- Warm Regards, Prashant Desai
