RE: Physically moving a volume
by Palmer, Jason (London) 31 Jan '01

31 Jan '01

Matt, You may need to refer to the rehoming a foreign volume bit on the NOW site. I have pasted relevent extracts below. ********** Extract 1 ********** Installing a foreign volume BM_1149726You can remove an entire volume from one filer and install it in another, which makes the moved volume a foreign volume to the filer. BM_1178353 Example BM_1178361For example, you might want to move a volume to a different filer to BM_1149727 * replace the volume's disk shelf with one that has a greater storage capacity BM_1149728 * gain access to the files on a dead filer BM_1149729When a filer detects a foreign volume at boot time, it places the foreign volume off-line. You can then bring the foreign volume on-line. For more information about installing and bringing up a foreign volume on-line, refer to "Adding <http://now.netapp.com/NOW/knowledge/docs/ontap/rel523/html/sag/disk5.htm#11 49886> a foreign volume." ********** Extract 2 ********** Adding a foreign volume BM_1149888To add a foreign volume, that is, a volume that was previously installed on another filer, you move the disks that contain the volume from the old filer to the destination filer. BM_1179040Complete the following steps to add a foreign volume. BM_1181660BM_1177101Step BM_1177103Action BM_11771051 BM_1177107Follow the instructions in the hardware guide to remove the disks from the old filer. BM_11771092 BM_1177111 Turn off the destination filer and install the disks in the destination filer's disk shelf. BM_11771133 BM_1177115 Turn on and boot the destination filer. BM_1177116 Results BM_1185503When the destination filer boots, it places the foreign volume off-line. If the foreign volume has the same name as an existing volume on the filer, the filer renames it volume_name(1), where volume_name is the original name of the volume. BM_1185881 _____ Caution: If the foreign volume is incomplete, repeat Steps 1 and 2 to add the missing disks. Do not try to add missing disks while online--doing so will cause them to become hot spare disks. BM_1185905 _____ BM_11855354 BM_1185564 If the filer renamed the foreign volume because of a name conflict, type the following command to rename the volume: BM_1185589vol rename oldname newname BM_1185565 Example BM_1185566The following command renames the volume vol0(1) to vol1: BM_1185567vol rename vol0(1) vol1 BM_11771225 BM_1177124 Type the following command to bring the volume on-line in the new filer, replacing volume_name with the name of the volume: BM_1177133vol online volume_name BM_11791026 BM_1179104 Enter the following command to confirm that the added volume came on-line: BM_1179129vol status BM_1149894 Destroying a volume BM_1149896To destroy a volume, turning its disks back into spare disks, follow these steps. BM_1181656BM_1177162Step BM_1177164Action BM_11771661 BM_1177168To deactivate the volume, enter BM_1177195 vol offline volume BM_11771702 BM_1177172Enter the reboot command to reboot the filer. BM_11771743 BM_1177176To destroy the volume, enter BM_1177211 vol destroy volume BM_1149900 Renaming a volume BM_1149902To rename a volume, follow these steps. BM_1181649BM_1177221Step BM_1177223Action BM_11772251 BM_1177227Enter BM_1177242 vol rename oldvolume newvol BM_11772292 BM_1177231Update the /etc/exports file and run exportfs. BM_11772333 BM_1177235Update any CIFS shares that refer to the volume. BM_1177293 Handling volume failures BM_1177295A volume might fail because of an inconsistent directory or a double-disk failure. If the system does not reboot after a volume failure, take the volume off-line, as follows: BM_1177296 1. Boot the filer from a system boot diskette into maintenance mode. BM_1177297 2. Use the vol command to take the failed volume off-line. BM_1177298If the failed volume was the filer's root volume, you must designate another volume as the new root volume. _____ There may also be issues with moving a root volume between filers ie 760 ----> 840. Just data volumes should be fine. I hope this is of help, Jason -----Original Message----- From: Matt Phelps [ mailto:mphelps@cfa.harvard.edu <mailto:mphelps@cfa.harvard.edu> ] Sent: 31 January 2001 16:44 To: toasters(a)mathworks.com Subject: Physically moving a volume All, We are physically moving a disk volume from a 760 to an 840 tonight. We're resonably confident about bringing up the 840 with the moved disks on it. The volume will come up as a foreign volume (it won't need to be renamed) and we'll just need to do a "vol online" command for it. It's not a root volume. However, the book says to check "your hardware guide" for instructions on removing the disks from the 760. We can't find this anywhere. Our current plan is to remove references to the volume in the various /vol0/etc files; shut down the 760, power it and it's shelves off. Remove the disks and just power everything back on again.

RE: FW: 2 q's - quotas and tape drives
by Ellett, Peter 31 Jan '01

Hi, There is a utility up on the NOW site call SecureShare Account Migrator and helps with the following: SecureShare Account Migrator converts users/groups from an NT domain into the format necessary to populate the /etc/passwd and etc/group files on a NetApp Filer. It creates the commands necessary to build CIFS shares for each user and applies appropriate rights to said shares. It also allows for syncing of an NT domain with /etc files, so you can run the program daily to keep your /etc files current. SecureShare Account Migrator is currently a beta release. Similar to SecureShare Account Migrator but in a command-line version, cvtusers can only be run from NT and requires access to NT kernel exports. It is the original incarnation of this tool. Here is a link to where you can find the SecureShare Account Migrator: http://now.netapp.com/NOW/download/tools/secureshaream/ Hope that this helps.

How does the cifs.homedir option play into this? I'm in the same boat, as I have to migrate 1300 CIFS user directories from an ailing NT box to one of my 760s in the damn-near future. -john -----Original Message----- From: Maglinger, Paul [mailto:PMAGLINGER@scvl.com] Sent: Wednesday, January 31, 2001 10:10 AM To: 'NetApps list server' Subject: FW: 2 q's - quotas and tape drives But if I use User quotas, then I will have to modify my usermap and passwd files to include all of my 250 NT users.

Unless I misunderstand you, you do not need a separate qtree for each user. Netapps provide both "tree" quotas and "user" quotas. A "tree" quota limits the total disk space of all files in a directory tree (quota tree), regardless of who owns them. A "user" quota limits the total disk space of files that are owned by a particular user. It sounds like you can do what you want with "user" quotas in one big volume with no qtrees at all. However, you may want to split things up for other reasons. "tree" quotas are typically used to limit the disk space of a project or department consisting of multiple users. And if you really like to micromanage, you can even have user quotas within a qtree. For example, fred user@/vol/vol0 15G - /vol/vol0/qt1 tree 25G - fred user@/vol/vol0/qt1 10G - Here "fred" can use up to 15G in the volume vol0. The qtree qt1 cannot use more than 25G of vol0. And inside qt1, fred can only use 10G. Any disk space that fred uses inside qt1 also counts against his 15G quota for the entire volume.

Virus scans on NetApps and backups
by Paul Letta 31 Jan '01

31 Jan '01

We are using Norton AV Enterprise 7.01 to scan our filer via CIFS. We have found that as Norton scans each file, the inode change time (i.e. ls -lc) gets set to the current time. I think it is due to Norton messing with the DOS archive bit, but I am not sure. The problem is that this turns our level 1 ndmp dumps into virtual level 0 dumps. It seems that ndmp uses the inode change time, not the file modification time, as a basis for picking which files to dump during level 1's. Any suggestions ? -- Paul Letta Thomas Jefferson National Accelerator Facility Computer Center Unix System Administrator EMail: letta(a)jlab.org Phone: (757)269-5106
