Re: [zfs-discuss] missing files on copy

2008-01-28 Thread Mark Ashley
It's simply a shell grokking issue, when you allow your (l)users to self name your files then you will have spaces etc in the filename (breaks shell arguments). In this case the '[E]' is breaking your command line argument grokking. We have the same issue in our photos tree. We have to use

[zfs-discuss] ISCSI LUNs changing size and losing ACLs

2007-11-29 Thread Mark Ashley
Hey folks, We're at Solaris Nevada snv_64a SPARC. We have a number of ISCSI volumes shared out with different sizes (1GB, 50GB, 10GB etc) and ACLs to limit which windoze machines can access what. We've had issues in the past with zpool devices being removed which resulted in corrupted zpools

[zfs-discuss] zdb internals?

2007-11-12 Thread Mark Ashley
I don't have time to RTFS so I was curious if there was a guide on using zdb, and does it do any writing of the zfs information? The binary has a lot of options which aren't clear what do what. I'm looking for any tools that let you do low level fiddling with things such as broken zpools. ta,

[zfs-discuss] Missing zpool devices, what are the options

2007-11-11 Thread Mark Ashley
We had a 'windoze' zpool on two internal disks. It had a number of zvols which were ISCSI'd out to a few hosts. This has been in and running for some months. Recently someone added some external SE6140 LUNs to the zpool as well, and last friday those LUNs were deleted from the SE6140 itself,

Economics for one. We run a number of testing environments which mimic the production one. But we don't want to spend $750,000 on EMC storage each time when something costing $200,000 will do the job we need. At the moment we have over 100TB on four SE6140s and we're very happy with the

Please don't do this as a rule, it makes for horrendous support issues and breaks a lot of health check tools. Actually, you can use the existing name space for this. By default, ZFS uses /dev/dsk. But everything in /dev is a symlink. So you could setup your own space, say

2007-09-04 Thread Mark Ashley
I'm going to go out on a limb here and say you have an A5000 with the 1.6 disks in it. Because of their design, (all drives seeing each other on both the A and B loops), it's possible for one disk that is behaving badly to take over the FC-AL loop and require human intervention. You can

[zfs-discuss] ETA of device evacuation?

2007-07-18 Thread Mark Ashley
Hi folks, One of the things I'm really hanging out for is the ability to evacuate the data from a zpool device onto the other devices and then remove the device. Without mirroring it first etc. The zpool would of course shrink in size according to how much space you just took away. Our
