Hi,

Unfortunately I have some free space issues on mail partition, and my client don't want to pay so much money for additional disk, so he would like to use pendrive, as a separate mail partition. As for emails, we do not store huge files, so pendrive should be enouth for that..

Server name is: Dell PowerEdge 1950.
There is no usb3 port, and I also don't wan't to buy usb3 controller, but buying usb3 disk, will be a good point anyway.

Please, could you tell me, what brand/model of pendrive, you will suggest me, to buy for that?

Thanks in advance,

Usually the mail spool resides in /var so I wonder: do you actually have a mail spool partition? Is it actually the mail spool directory that's the problem or is /var just full? And if there is another partition with enough free space you could probably copy your mail spool directory there, rsync if necessary then 'mount --bind' it over the original mail spool directory?..

I'm surprised that where you live disks cost less than pen drives. I'm in the UK and can buy a new 80GB IDE hard drive for £13 or a 160GB SATA drive for £17 from a local online store.
That's cheaper than only small USB sticks and I'm sure that hard drives are available cheaper than that especially if willing to go second hand.
Or am I misunderstanding something here?

A second hand hard disk inside a server? Deities! Thou must be jesting...

I wasn't entirely serious, no. However I'm not convinced using a pen drive is all that safe either but, then, that's probably just me.

unSpawn: yes, I have a separate partition for mails: /var/mail/ and all mdir's are there. Accualy I have 14G/15G in use.

273: Hard disk and hard drive caddy is some kind of cost (I always buy a new stuff), and pendrive have no plates, so could be quite fast for small files transfer.. That's why I am asking for pendrive, and this kind of solution.

Well done answering only one of three questions I asked.

Sorry!
1. I have separe /var/mail/ partition, which is going to be full soon.
2. /var/ parition have some free space. No issues.
3. No, there is no other partition which have enought free space. All other paritions have about 2gb of free space.

OK then. Since you've exhausted your options (I suppose there's nothing you could remove or move elsewhere and NFS mount?) another disk would indeed be the option. Personally I'd go for a larger server-grade hard disk and migrate the whole OS and data over.

Migration is a money. But this is in plan for next year.. For now, I would like to add pendrive..
Let me know your opinion what kind of pendrive will be the best?..
